    Lightroom 4 hangs on opening

    ChasHertz Community Member

      When I open Lightroom 4, it will not infrequently (every day or two or three) hang -- typically images are visible in the filmstrip, but the central work area just says "loading," and if I try to click on anything, the little Windows circle starts spinning indicating that the program is hung.  All I can do is use Task Manager to kill the program.  Re-starting the application invariably leads to the same result.

       

      I have discovered a simple solution.  I go to the c:\users\username\appdata\roaming\adobe\lightroom folder, delete the preferences file, and now Lightroom will open without problem.  But now the problem is that I have lost my preferences.  No big deal, but it takes me a minute or so to set the preferences back to where I want them.

       

      Reset the preferences, or leave them in the default settings, doesn’t matter:  I know for certain that at some point in the near future Lightroom will hang again, and again I will have to delete the preferences file to fix things.

       

      I have uninstalled and reinstalled multiple times, to no benefit.  I have even combed the registry after uninstalling, deleting every remaining reference to Lightroom or LR4, all to no avail. I should add that I had the same problem with Lightroom 3, but it happened much less often. 

       

      I am running Windows 7 64-bit.  It's a very clean system, all Windows updates installed, never any malware, only standard, commerical applications installed.

       

      Any ideas?

          Your problem is identical to my problem.  LR4 hangs when opening.  Images are visible in the filmstrip, the central work area dialog box says loading, but when I try to click on anything, the infamous mouse cursor changes to a circle and starts to spin - forever.  I also have to close the program using Windows Task Manager.  I can never get LR4 past this stage.  I have uninstalled and reinstalled - no changes.  Yesterday I loaded newest LR4.1 RC - no changes or improvements.  I have a very current next generation computer system, powerful, Win7 64 bit, 6 GB memory, current updates.  Longtime user of LR, including LR3.6 - never any problems in the past.  Now even 3.6 hangs.  Very frustrating, as currently all versions of LR on my computer are unusable!

           

          I will try what you note above as a workaround and will update a new post.  I will also be speaking with Adobe Technical tomorrow and will update any "long-term" solutions.

            It worked - your workaround of deleting the preference file allowed LR4 to open normally.  Wow!  Now if only we could find a long-term solution.  As you note, the preference file will need to be deleted again and again, not what any of us signed up for.  If you learn of any long-term solution, I would be very interested.  I will keep you posted as well.

              Well, I'm sorry you're having trouble.  But after spending an hour or two with Google and coming to the conclusion that I was the only person in the world with this problem, it's comforting to know there are at least two of us.  I upgraded to 4.1RC after posting the notice, and was hoping that might somehow do the trick (I wasn't put off by the fact that 4.1RC didn't fix it for you, since when you installed it your preferences file was presumably already corrupt [if that's indeed what's happening]), but I can now report that it didn't solve the problem, LR hung up again, and I fixed it again by deleting the preferences file.

               

              I will absolutely post any progress here, and thanks in advance for the same.

                Okay, a little more information.  I opened LR4.1, changed all my preferences to the way I wanted them, then closed the program.  Then I copied the preferences file to my desktop.  Opened LR4.1 again, and it still worked, confirming that the preference file (a copy of which was now on my desktop) was okay.  Then I opened and closed LR a few more times, until it finally hung.

                 

                This time, instead of just deleting the preferences file, I replaced it with the desktop copy.  And now all is well, my preferences are intact.  Obviously, this doesn't solve anything long term, but now the workaround allows me to keep my preferences.  So it's still very annoying, but less so, and if necessary I can manage this way indefinitely, assuming nothing else goes wrong.

                 

                I would note that the preferences file I saved to the desktop was about 20KB, and the "bad" file was larger, 30KB.  I made no changes in my preferences after saving the copy.  So it looks like something is corrupting the preferences file, as I had previusly supposed.  Probably some subtle bug that only shows up under some peculiar set of Windows 7 settings, installations, whatever.  Given that there are, so far, only two of us, I'm not optimistic that the problem is going to be solved.  Maybe LR5...

                  So, here's a suggestion:  Make a copy of the "good" preferences file, as above, then open and close LR until it crashes, then save a copy of the "bad" file.  When you speak to tech support, offer to send them both files.  I did a Command Prompt fc (file compare) of the two, and it spits out a number of differences in plain English, clearly various parameters or preferences.  E.g. one file contains AgColorPlopup_Phase=0, the other does not.  I have no idea what to make of the information, but it may well mean something to tech support.  There's something in the "bad" file that's crashing LR.

                    Very good suggestions - thank you for the feedback.  I find it ironic that you were posting on the forum for some help, and you end up helping me in the process.  I guess that is the way these forums work - we end up helping each other.  I agree with you in that I am not confident Adobe will provide a quick fix for the particular problem you and I are experiencing, due to the fact if you read through the other forum threads, not many seem to be experiencing this exact same hang issue where the program is not usable, albeit there seem to be many other problems.  As noted previously, I will be speaking with Adobe Technicians tomorrow and will let you know what they say.  Thank you again for the good feedback noted above.

                      Okay, thanks.  I have a horrendous week coming up at work, and just don't have time to call tech support, and I appreciate your taking the trouble.  Let me know what, if anything, you learn.  If you don't get anywhere, I can probably call them next week, so at least they'll know that more than one person has the problem.

                          Anytime LR crashes or fails to open properly (i.e. hangs) there is a possibility for the Preferences file to be corrupted, but it’s not likely that’s causing the “initial hang" every few days.

                           

                          I’m finding both LR4 and LR4.1 RC are fairly slow on the first launch (~30 sec.) after initially booting up my Windows 7 SP1 64bit system, but subsequent launches are pretty fast (~10 sec.). Do you do regular catalog backups with the options for 'Test integrity before backing up' and 'Optimize catalog after backing up’ selected?

                           

                          I’ve seen the same type of “hang” when opening other applications and trying to use them before fully launched. The Windows circle pops up and starts spinning, the screen loses contrast and hangs forever, requiring launching Task Manager to close it out. I never had this problem with Windows XP, so it appears to be something unique to Windows 7 based application operation. Try waiting for LR to fully launch before clicking anywhere inside the app window.

                           

                          Other less likely possibilities are hard drive fragmentation or memory problems. You can try defragmenting your drive(s) and running a memory diagnostic test to rules these out.

                            Those are all reasonable points.  However: 


                            I am running a fast HP workstation, with 15000 rpm SAS drives in RAID 0 configuration, and normally LR4 opens and is ready to go in a matter of seconds.  Nevertheless (since the Windows spinning circle doesn’t show up until you click something), I have tried opening LR4, then walking away for a cup of coffee.  On my return, the central work area still says “loading,” and clicking anywhere brings up the spinning circle, which I have watched spin for up to ten minutes before bringing up Task Manager to kill the application.


                            Once it hangs, the ONLY thing that fixes the situation is to delete the preferences file, or, better, replace it with a saved copy.  And that ALWAYS fixes it. 


                            I have tried uininstalling and reinstalling, which doesn’t help at all if the preferences file remains intact.  I have also tried using a backup copy of the catalog, tested, optimized, and then verified, and that doesn’t help at all.


                            With regard to fragmentation, my drives are continuously defragmented with Diskkeeper.


                            Memory (12GB) seems fine.  And I use multiple other applications, including Premiere Pro, with nary a problem.

                             

                            But I appreciate the suggestions, and please let me know if anything else occurs to you.

                              Chas: I did make contact with Adobe Tech, and they recommended the same action - remove the preference file and re-launch.  I told the tech this is good for only a couple of launches, and he had no other suggestions or recommendations.  I am going to call again this next week, and see if another tech will come up with something else more permanent.

                               

                              trshaner:  I appreciate your feedback as well, good recommendations in your April 5 comments.  However, I am having the exact same experience as Chas.  After launching LR4 I can go out and mow the lawn, BBQ a couple of steaks, and down an IPA, and LR4 will still be hanging upon my return.  After shutting down the program with Task Manager, the only thing that fixes it is to delete the "Preference" file, and re-launch the program.  For me, the hanging happens about every other launch, so I have to delete the preference file again and again.  This process always fixes the problem immediately.  Or as Chas noted, I can keep a copy of a good preference file located elsewhere, and reinsert it into the LR preference file - and the program will launch appropriately. The problem is definitely preference file related - somehow corrupting the file when shutting the program down, setting up future launch failures.  Very frustrating.

                               

                              System type as follows:  win7 64-bit ver 6.1 sp1 / x64-base pc / intel core i7 940@2.93 GHz 4 cores / 6 GB physical memory (RAM) / ATI radeon HD 4870 x2 / 2 each WD Raptor 10,000 Drives Raid O / 2 each WD 7,500 Drives Raid 1.

                                I've passed on this thread to the Lr team but wouldn't expect any response over the holidays.

                                Thanks for your efforts in trying to isolate this.

                                  Thanks!  I can pass on copies of "before" and "after" preference files, i.e. good and corrupt, if you think it would be helpful -- if so, can you provide an email address? As I mentioned above, the "after" crash file is 50% bigger, and appears (when I use the Command Prompt fc command to compare the two files) to contain multiple parameters not in the "before" file, meaningless to me but perhaps meaningful to someone more knowledgeable.

                                    I'm beginning to wonder if the problem is related to the "fast" load time of LR, due to your fast RAID 0 SAS 15K drive array speed. You say: "normally LR4 opens and is ready to go in a matter of seconds." I'm seeing about a 30 sec. on initial load with my 10K SATA single drive Windows 7 system with subsequent loads about 10 sec., and I have no issues. Apparently LR is doing some processing in the background during launch, and perhaps the fast transfer time of your drive array may be "occasionally" over-stepping these background processor based steps during launch. I used to design real-time OS based systems and these types of issue required code changes (timers, etc.) to correct problems across different speed platforms.

                                     

                                    Java Magellan, just out of curiosity what type of drives and configuration are you using? Also for both of you, are you using any plug-ins, such as Nik, etc.

                                      Interesting idea. 

                                       

                                      I'm not quite sure what you mean by "initial load" and "subsequent load."  In any event, LR4.1RC opens for me, and is ready to go, in just under 5 seconds.  I have a relatively small catalog, about 10,000 images.

                                       

                                      Java Magellan's drives/configuration are above, in a reply to me (item 11).  We both have pretty fast systems, but surely there must be lots of others with similar systems, yet our problem seems to be shared by very few others (if any).  That's why my guess is that there's some peculiar and idiosyncratic combination of Windows settings, other applications, etc., that just happens to have hit us.  But I'll be the first to admit I have no technical background as you do.

                                        Sorry, didn't see that Java Magellan's has a similar fast RAID 0 10K drive array config. So it may be due to LR4's behavior on systems with fast hard drive RAID 0 arrays, based on 2 for 2 with same setup.

                                        By initial load I mean the 1st time I launch LR4 after boot, which loads the image into memory (~30 sec.). Subsequent launches after closing out this 1st launch are much faster, but still about 10 sec. I'm running on Win 7 Home Premium SP1 with a 2.8GHz i7 860 quad-core system, 12 GB memory and a single 1TB 7,200 RPM (not 10K) SATA drive (Hitachi 1TB HDS 721010KLA330).

                                          Lightroom takes about 15 secs to launch for me on a Mac i7 with the catlog on the internal 750GB 7200 drive.

                                            LR4.1RC takes about 3 secs to launch into Library on my Win7x64 - using ssds for system and catalog/previews. So the problem can't just be speed of launching - I don't have any problems with corrupted prefs files.

                                             

                                            I would try exporting your whole catalog+previews to a new catalog. That can get rid of stuff in the old catalog that is upsetting something in LR4. Especially if your catalog is an upgraded one from LR3.  This has cured several strange problems for me in the past, especially when upgrading from LR2-3 and now LR3-4. Noting to lose except any Publish stuff you have stored in the catalog.

                                             

                                            I usually just export the catalog, without the old previews, and make it create new previews and previews.db. Takes a lot longer, but worth it in my opinion.

                                              Ah, I see.  Actually, I can't tell the difference between lauching after re-booting, and subsequently -- in both situations, it's less than 5 seconds. But see bob frost's comments (item 18 in this thread).

                                                Well, your system is faster than mine, so I agree, speed of launch wouldn't seem to be the problem.

                                                 

                                                I have been using Lightroom only since February, and have been working my way through several books, Adobe's and Scott Kelby's.  (And asking myself why I didn't do this years ago; what a terrific applicaton LR is!)  Anyway, 99% of the work I've done has been on test images provided by the books,  so in the process of investigating the LR4 problem, I have without hesitation deleted my catalog and re-created it from scratch, after uninstalling and reinstalling LR4,on at least 3 occasions -- no help at all, unfortunately.

                                                 

                                                Note that this is (like all frustrating computer problems) intermittent.  It happens to me maybe every fifth time I lauch LR, though Java Magellan says it happens every other time for him.

                                                  Found this thread today looking to solution to the same problem. Thought I could add some info as well perhaps. I hadn't thought about fiddling with the preferences file, but I did get into the task manager and find that after I shut down lightroom and later try to reopen it (and can't) if I look under the processes tab, there are several "lightroom" instances running, one is using typically over a gig of memory, the others are significantly smaller. If I kill all of them, then I can open lightroom just fine. Never have fiddled wtih the preferences or anything, just killing the processes. I appears to me that it's not exiting gracefully enough and is leaving tidbits running in the backgroun and subsequently not releasing resources, and that then prevent it from reopening.

                                                   

                                                  FWIW, my machine specs are pretty strong as well - home built Intel Core i7 2600k (but not overclocked currently), 16 gigs of ram, 256gb SSD (OCZ vertex 3) for system drive, nvidia GTX560/1gb video.

                                                    I’m not sure we’re having the same problem.   If I open LR, and it hangs, Task Manager shows the LR application (“not responding”), and one process, lightroom.exe.  If I shut down the application, then the process also disappears.


                                                    If I re-launch LR, same thing:  one application (not responding), one process.  Shut down the application, the process again disappears.


                                                    When you say you can’t reopen LR, do you mean it literally doesn’t open at all, or that it hangs after opening but before displaying anything in the central area?  My problem is the latter.


                                                    Delete the preferences file, or replace it with a saved copy of a good file, all is well (until the next time it decides to hang).


                                                    Again, I think we’re having different problems, but have you tried deleting the preferences file?  Does that fix it for you?

                                                      my apologies - I believe you are correct in that it is probably a different issue. What I've had occur is when you try to reopen lightroom, I'll get the usual "circle" icon that it's loading but then after a few seconds, it goes back to the regular arrow cursor and the program never load/runs, so I'm not even getting out of the gate. The number of instances of lightroom in the processes list seems to correlate with the number of times I try to open it unsuccessfully..... I'll try fiddling with the preferences and see what happens

                                                        Also check to see if the is a .lock file next to the .lrcat file where your catalog is located. If there is a lock file, delete this (with Lightroom closed).

                                                          I too am having major problems with LR4 not opening-- I am running Vista64 with 8GB-- It opens in a jiffy after first install. Second time of opening it gets no further than a 'server busy' dialogue with options to switch to, try again or cancel, none of which do anything. deleting prefs and /or rebooting does not work. All I can do is uninstall and reinstall from scratch.

                                                          I have used LR daily from version 1 and Pixmantec Raw shooter before that, I hope they can sort this bug soon.

                                                          Sadly I have work to put out for tomorrow from a G1X which is not supported on LR3x otherwise I would say stuff it an revert to version 3.

                                                          Very frustrating.

                                                            Still having trouble?  Yesterday I downloaded and installed LR 4.1 Release Candidate 2 (released 4/26), and it seems to have fixed the problem.  I have opened and closed Lightroom at least twenty times without mishap.  I guess there's no way of being certain, but I don't think I've done more than 5 or 6 cycles in the past without running into the hanging problem, and having to copy in a "good" preference file.

                                                             

                                                            Try it, if you haven't already, and let me know what happens.

                                                              Sorry about disappearing for the last month - buried with work.  With regards to the hanging issue, interestingly I have been able to open and close LR successfully over the last 6 or 8 times without issue.  In the past, I was not able to open more than once or twice before the problem would show up.  There is no explanation - I did nothing different.  It just seems to be working lately, although I find myself crossing my fingers each time I open the program.  I expect the problem will return however, therefore I am going to search out and install the newest LR 4.1 RC 2 that you reference.  I'll let you know how it works out.  The good news is we are both having some success - even if we do not understand the cause.  Thanks again for the info.

It needs a little bit time to scan all the lens profile and camera profile database and build up a database cache. Once that is done, the subsequent launch should be much faster.

My Laptop is no where as near as good as those above, an i7 Win 32, 4Gb memory with 500Gb dedicated drive for data files and 500Gb for system. I have been using LR since 2.0.. and have over 40K of images. I religiously backup, and test the integrity of the database, although I haven't tried exporting it to a new database.. something for later perhaps..

                                                                           

                                                                          LR continually hangs during operations.. usually within the develop module.. and I have to continually close it down, sometimes forcibly with task manager, but mostly just close it down and re-start. It then runs okay for 5-10mins and then happens again. As it is not a work task.. just an expensive hobby I have been tolerating it.. but no longer... rrrr

                                                                           

                                                                          I will try the RC2... I had downloaded the RC1 but hadn't installed it... wasn't game enough.... gulp..

The final release should be coming soon, and hopefully that may solve all the problems people are having - fingers crossed.

                                                                            If you are still using previews updated from LR3, I would delete them all (including the previews.db and rootpixels.db and the acr cache) and then tell LR to rebuild all previews (from the Library menu) - overnight if you have a lot. That tends to make things run more smoothly from my experience. Exporting your catalog to a new one can also get rid of old stuff from LR3 that might upset LR4 - I always do that after an upgrade, and it has improved things IME. Similarly deleting your preferences file (and the older LR3 pref file if it is still there) and creating a new one has worked wonders for some people.

                                                                              But if I can open LR without the problem, then it NEVER hangs during that session, no matter how long or complex it is.

                                                                              • 37. Re: Lightroom 4 hangs on opening

                                                                                Okay, here we go again.  As I mentioned, LR 4.1 RC2 was NOT the answer.  In fact, the initial hang-up started happening almost every second or third time I’d open LR – and as always, the problem would be fixed by copying in a “good” pref file.


                                                                                As you may know, the official release of LR 4.1 occurred a couple of days ago. Easier to find than the release candidates, just open LR, go to Help > Check for updates, and it will offer to download 4.1 (be patient, it’s 748 MB!).  I have installed it, and have had no problems since then, at least twenty iterations.  Hope this isn’t another false alarm.


                                                                                Just FYI, I did a complete uninstall of the previous version before installing the new version, and I deleted the preferences file, to force the new version to create its own.  I didn’t delete the catalog or comb the Windows registry and delete every reference to LR that I could find, as I have tried in the past, so it was all fairly painless.


                                                                                The new preferences file, which I updated to match my previous set of preferences, is slightly smaller (19 KB) than the one created by previous versions, so it appears something has been changed in that part of the program.  I check the file every time I shut down LR, and it hasn’t changed in size, so far.  Fingers crossed.


                                                                                Let me know what happens when you try this.

                                                                                  I don't think anyone is still following this conversation, but I thought I'd add this note, in case someone with this problem stumbles across these posts.

                                                                                   

                                                                                  LR 4.1 worked great, for a week, probably opened and closed it more than 50 times without mishap.  Then the old problem resurfaced, and in a matter of a day or two it was hanging every time I opened it.

                                                                                   

                                                                                  So I created the following batch file in the Lightroom directory, and added a shortcut to it to the Start menu.  Works great, and seamlessly, LR opens without any pause.  Note: I created a subdirectory named "good" in the preferences directory, and stored a good preferences file there.

                                                                                    Hi Chas:

                                                                                     

                                                                                    The fact that I disappeared for so long is a sign that things were working smoothly for awhile.  Sure enough however, I downloaded the most current version LR 4.2, and the same old problem began to haunt me.  The infamous death spiral where the program does not fully load, and the only solution is to kill the program with Control/Alt/Delete.

                                                                                     

                                                                                    With the above said, I went back online and found your most recent June 7 post.  Once again I find your information very helpful.  I did just what you noted above, and was able to get the program to open.  In fact the program opened faster than ever before - fully loaded within 15 seconds.  I must admit however that I have no confidence the problem is gone, and fully expect a repeat soon, but I'll let you know.

                                                                                     

                                                                                    Question for you:  When you say you created a "batch file in the Lightroom directory", I am not sure what you mean by this.  Can you elaborate?

                                                                                     

                                                                                    Thanks again for the good information.  Regards.
