    aztecvision: I think I'm having the same problem. I've been using Lightroom 4.2 on an HP Windows 7 machine for months without problems.  All of a sudden it refused to start the other day, giving me the following message:

     

    • The application was unable to start correctly (0xC000007B)

     

    I've read just about every message on the forums to no avail.  Perhaps we can help this out together.  A few questions for you:

     

    • When did you last successfully run LR?  When did you notice it was broken?  (I successfully ran LR on 11/4 and discovered it broken on 11/7.)
    • Have you installed or uninstalled any software?  In particular, did you install iLivid or uninstall the HP Support Assistant?  (In my case, a family member had foolishly installed the former, and I had uninstalled the latter.)
    • Did Windows apply any updates?  (There were a few on my system, but I think they were just virus definitions.)
    • Have you tried doing a system restore to an earlier restore point?  (You might want to backup your computer before doing this.)

     

    Following the advice of the forums, here is what I tried to fix it.  None of these things worked:

     

    1. Uninstalling iLivid.
    2. Trying to do a Windows system restore from an earlier point.  (This is not a backup restore; it changes registry and program installs.)  I was able to do this successfully from one point, but it didn't resolve the problem.  After undoing the restore, I was not able to go back to any of the earlier restore points, getting a "catastrophic failure message".  I also tried the restores from Windows safe mode, but this had the same problem.
    3. Running "chkdsk /r", which didn't find any problems.  I also retried (2) after this to no avail.
    4. Running a full MS antivirus scan which didn't find anything.
    5. Uninstalling all versions of LR and reinstalling 4.3-RC1.
    6. Reinstalling the HP support assistant.
    7. Uninstalling LR with the MS program install/uninstall tool, which is a replacement for the msicuu2.exe, then reinstalling.
    8. Running the Adobe CSS cleaner and reinstalling.

     

    Finally, I installed the 32 bit version of LR-4.3-RC1 by manually running setup32 from the LR install directory.  This worked!  But it's less than desirable since the performance is presumably less than the 64 bit version.  I'd really like to figure this out.

    DH: I'm not surprised that uninstalling iLivid didn't solve the problem.  It didn't work for me.  Also, I'm not sure what you mean by "from a disc".  I presume you mean installed via CD instead of a download.  I doubt that would make a difference.  It is interesting that your LR 3 still works, because mine didn't.

     

    I found a third person who can relate this problem to iLivid (http://forums.adobe.com/message/4839230), so I think we're on to something.  I've emailed iLivid support for some guidance.  In the meanwhile, you could try a Windows system restore to before you install iLivid.  I'd be really interested in the results of this, because it should in theory solve the problem but it didn't work for me.  It's easy, just type "system restore" in your start menu, then chose a custom restore point. But I'll warn you: you really should back up your computer before doing this.  Don't blame me if your computer breaks.

     

    If you don't want to try that, you can always use the 32 bit version--which might be slower--or wait to see if I can find more information.  I think the next step might be to try some Windows forums.

    I'm haaving the same issue with lightroom 3. Also after installing iLivid and uninstalling. I have just upgraded to windows 8 and this made no difference. Everything online seems to point in circles, someone asks about the issue but just gets pointed to someone else asking with no real solution.

    drevil270183: you're now the fourth person who can confirm the problem is related to iLivid.  This is disconcerting. I hope iLivid responds to my support inquiry.

     

    If we really want to dig deeper, I suspect we might have to do some detective work.  Here's a proposal:

     

    1. Find a Windows 7 computer that has never had iLivid installed.  Maybe someone has an extra computer or is willing to wipe the hard drive.  Or perhaps someone could set up a fresh install in a VMware instance.
    2. Install LR 4 and make sure it works.
    3. Take a snapshot of the hard drive and registry.
    4. Install iLivid.
    5. Verify that LR no longer works.
    6. Compare the hard drive and registry with that of step (3).  I suspect we'll see that some DLL's have been modified.

     

    Any volunteers?  My hope is that we learn something in step (6) that can lead us to a solution.  Unfortunately I don't have an extra computer or VMware instance to do step (1).

     

    If you really want to do a pro job, take a video of the work.  We can use this to show iLivid the problem, or post it on YouTube if they don't respond.

    Hi all. I'm happy to do that - I've a spare HD that can use to install a clean Win 7 64bit install and do a pre/post iLivid comparison. I'll try and do it tonight - wife and kids permitting!

     

    I'll post back my results.

    Thanks, w7r!   I hope your family is understanding.   I've never done this sort of pre/post comparison, but a quick Google search gives some tips

     

    Also, I definitely encourage you to set up a video camera on a tripod, as this gives definitive proof. We can always edit the video down later.

    Hi guys, I sorted it on my PC. It may or may not work for you but this is what I did.

     

    I uninstalled Lightroom 3.2 for my computer.

     

    Ran my lavasoft Virus Software which found some dodgy stuff and got rid of those.

     

    I then downloaded some free registry clean up software and that ran through the programs currently on my pc and cleaned those up and then the registry too.

     

    I then rebooted and installed lightroom again. So far it all works fine.

    Hi guys. okay - bingo!

     

    1. install fresh 64bit Win7

    2. created system restore point pre LR 4.2 install

    3. installed LR 4.2 - rebooted

    4. ran LR 4.2 - worked fine

    5. created another system restore point pre iLivid install

    6. down iLivid and install

    7 ran LR 4.2 and bang got the error message we've been seeing.

     

    Didn't have time to set-up a video camera but could try and find time later in the week.

     

    So, finger pointed fairly and squarely at iLivid

    w7r: thanks for doing this!  Have you found any obvious differences pre/post install?  I can help analyze if you send me directory listings before/after as text files.

     

    drevil: that is really interesting.  I ran two MS antivirus programs which didn't find anything.  Did you notice what exactly Lavasoft removed?  Did you try LR after this but before the registry cleanup?  Also, which registry cleanup tool did you use?

    w7r: on second thought, maybe you should try running Lavasoft and seeing what it removes.  That might be easier than trying to diff pre/post.  Of course, this assumes w7r doesn't remember what Lavasoft removed from his computer.

    I just ran Malwarebytes on my computer.  It found and removed a bunch of stuff.  Alas LR-64 still fails to start even after reinstalling.  I'm going to try Lavasoft AdAware, but I'm not optimistic.  Even if I get LR-64 working again, I will worry that my computer is hopelessly compromised.  I may need to just reinstall Windows.

    I am having the same problems, only with Lightroom 4.2 64 bit on my 64 bit Windows 7.  It began by failing to open when I had Lightroom 3.2 installed, a few weeks ago.  I was planning to upgrade to version 4 anyway, so ordered it hoping that it would solve the problem.  It didn't.  I installed the 32 bit version, but it is very slow and runs out of memory with my large raw files - it can't use the 16MB installed memory.

    I have heard of iLivid, but there is no trace of it on this machine.

    In trying to fix the problem, I ran chkdsk /r and fixed some errors.  It must have zapped some system files, so I had to do a Windows repair (what a pain).  And, it did not fix the problem.

    Per the above posts I will run all of my virus scanner software and CCLEANER and see if it fixes anything.

    I installed Ilivid and now my lightroom doesn't work.  I am going through a divorce and my husband used to help me with my IT stuff and I am not smart with this at all.  It looks like from the comments above I will have to reinstall Windows.  Any tips on how I do this without the disk?  Also, when I do this will my library and presets in Lightroom be saved.

     

    Thank you in advance :-)

    I am having the same exact problem with my LR4 since having installed iLivid.  64 bit version worked fine up until that point, now I get the Error 0xc000007b message.  Went ahead and installed the 32 bit version and that seems to work fine.  Uninstalled iLivid and 64 bit version still does not work.  Hope to hear of an easy fix soon!

    Jodi, without going into deep stuff, I will answer your questions.

     

     

     

    First, you may not have to reinstall Windows – that is a last resort.  That being said, you will probably need a Windows install disk to do it.  If, however, your PC manufacturer installed a copy on a hidden disk, you could activate it while you are booting up the PC.  Beware, however, you will lose every program and all the data you have installed – the PC will look just the way it did when you first received it.  So – last resort.

     

     

     

    I would watch the forum here closely.  The guys and gals have pinned it down to iLivid being the culprit.  I am running a whole bunch of virus removal products right now and, if I am successful, will be able to recommend one – a lot easier than reinstalling Windows.  In the meantime, run the 32 bit version.  It works OK – just slow.

    After restor an old version of Windows 7, before install Ilivid, "Panneau de configuration" and "recuperation" in french language.

    uninstall Lightroom and reinstall LR64 for a right connect with the catalog, all OK .

    Foolish question, how do I run the 32 bit version.  Seriously, thank you so much for the help.

    Hi guys,

     

    I uninstalled lightroom, ran lavasoft virus checker which might not have done much. http://www.piriform.com/ccleaner  this is the registry cleaned I used and did all the checks it offers. restarted the computer and installed lightroom. Works fine now. Give that cleaner ago, it seemed really good.

    No question is foolish the first time you ask it!

     

     

     

    First, download Lightroom version 4.2 from the website, if you have not already.  Although it depends upon what Internet browser you are using, the download will usually end up in a folder called Downloads and it is called Lightroom_4_LS11_win_4_2.exe.  Your browser may show you the download in a list.  When you have located it, double left click on it to run it and wait patiently.  It will ask you two questions – reply Run, then Next to them.  Then wait again.

     

     

     

    An Installer window will pop-up and give you two check boxes.  Click on the first to uncheck it, and click on the second to check it (Open Specified Folder) and click on OK or Run or Continue (whatever it says…).  In the Windows Explorer window that pops up, double left click on the folder called Adobe Photoshop Lightroom 4.  There you will see two files, Setup32.exe and Setup64.exe.  Double click on Setup32.exe to install the 32 bit version of Lightroom.  You do not have to uninstall the 64 bit version, but you will have two icons on your desktop.  The new one is the 32 bit one.  Whew!

     

     

     

    I have not had success so far in getting the 64 bit version to run, despite running various malware scanners and registry cleaners, etc.  I manually removed all references to iLivid from the registry too.  I suspect that iLivid installed a file with the same name as a (minor) system file, replacing it.  Running SFC /scannow and even doing a full system repair has not replaced that file with a good one.  I need to see a manifest from iLivid to see what files it installs.

    Drevil: thanks for the tip on ccleaner. I'm traveling now but will try it when I get back. Has anybody else had luck with ccleaner?

     

    If anyone wants to dig deeper, we still haven't figured out exactly what Ilivid is changing. W7r was kind enough to finger ilivid with a fresh install. Perhaps someone with IT experience could diff the system files per my suggestion above?

     

    Everyone might want to consider sending mail to Support@ilivid.com describing your problem. Be polite! Never attribute to malice what can be explained by incompetence.

    Guys - think I have the solution. I too like everybody here started seeing this error subsequent to iLivid installation. After reading through the logs here and elsewhere, I started tracking down the issue and eventually zeroed in on the following DLLs:

     

    1. msvcr80.dll

    2. msvcr100.dll

     

    These DLLs were reported either missing or being 32 bit. I am runnig Win 7 Enterprise 64 Bit. After copying the 64 bit versions of these DLLs in the Ligthroom installation folder, I was able to run Lightroom 4.3 RC.

     

    Hope this helps.

     

    Background Info:

     

    1. I was running Adobe Lightroom 3.6 64 Bit

    2. I installed iLivid, and Lightroom started bombing with oxc0000007b error.

    3. I uninstalled iLivid, deleted ALL traces of it from Registry, ran multiple registry cleaners several times.

    4. Ran LR 3.6 but oxc0000007b error persisted.

    5. Uninstalled LR 3.6 and then installed LR 4.3 RC - the same error.

    6. Then tracked down the issue to those 2 DLLs.

     

    My LR is working fine now.

     

    Let me know if this worked for you.

     

    Regards//K

    I can confirm that the above solution with the DLL identified works. I just uninstalled 4.3 RC and installed LR 4.2 and the same oxc0000007b error came up when I tried running LR. Then I copied the DLLs into the installation folder of LR 4.2, and voila! It started working. Now, I do not know the reason for this, but the DLLs indeed seem to be causing this error.
