For those still having issues:
To All who signing out and signing in isn't resolving for you and are on Windows,
This could still be licensing related---
What if you try renaming both the SLCache and SLStore folders prior to launching Lightroom?
Locations of both of these folders are located in Solution 3 of this document: https://helpx.adobe.com/lightroom/kb/unable-launch-lightroom-55.html
If you'd like to change permissions first as a test, then renaming the folders and report back the findings of both methods, that'd be great!
Let us know how it goes.
I cleared the files in the SLStore folder and it started!
Tried rebooting, signing out and back in, tried to start from the .exe file in explorer. No joy, but strangely updates to Muse and Bridge installed during the same session are working fine.
Wouldn't it be nice if Adobe actually employed some customer support people to solve these issues, instead of taking the cheapskate option and relying on knowledge sharing by their customers for product support? I wonder how a car manufacturer would go delivering service via a user forum??
Same here does the same thing. I've already uninstalled LR5 and tried the installation of Lightroom CC at least three times. I hope a fix come quickly this is unacceptable.
Just been given a fix by adobe .. On mac 10.10.3 yosemite
Sign out of cc
Press Command-Shift-G and type /Library and hit enter.Navigate to Application Support/AdobeOpen SLCache folder and delete all the contents.Go back and open SLStore folder.Delete all the contents there.Open the Creative Cloud app again and sign in.Open Lightroom now.
Sign in and out worked for me (the second time). Hope it will work for you as well.
Sign out of the Creative Cloud App. Make sure you're using the most up-to-date version of the CC App before you do it. Sign back in with your Adobe ID and password, then launch LRCC. It works.
It is embarrassing that Adobe repeatedly undermined such errors. Actually, Adobe should be responsible for damages caused by such sloppy work.
It seems that if you log out of your Creative Cloud account totally then login again the problem fixes itself, another one of Adobe's quirky things, managed to get my help from Lightroom CC Crashing at Launch? Here’s How to Fix It - it solved the problem for me totally.
I was having the same issue... install went successfully but Lightroom CC wouldn't start. I resolved the issue by rebooting my computer, opening Creative Cloud, signing out then signing back in again. App started perfectly after this.
Had the same problem. Signed out of CC and signed back in...LR CC now launched. Can I delete the old lightroom app now??
Thank you all that responded. I followed your advice and WA-LA like magic it worked.
Thank you so very much
Signed out and then signed back in and it worked for me on my Mac!
Signing in/out didnt work. Deleting the contents of (but not the folder itself) of SLCache fixed it. On Win 8.1
I have exactly the same problem so I have uninstalled it- just seen about signing out and signing back in so I will try that
Hardly an elegant solution for a class act like Abode. I'm sure there are some red faces in San Jose.
Not sure if this will work for anyone else, but it worked for me. Had the problem of Lightroom CC not opening. Signed out of CC and signed back in as me. Still would not run. Signed out and signed in using my wife's account. Still Lightroom CC would not open. Signed out and signed back in using my own account. This time, Lightroom CC loaded and seems to be running just fine! Not logical, but it worked for me.
This worked for me, thanks!
Thanks that worked
Logging out and in does not work for me. WIndows 8.1. Lightroom CC, trial.
Did you log out or just exit the program (as I tried the first time and
In the CC app you must go to the settings (gear)>>preferences>>logout.
Hopefully they'll get this fixed.
I did everything. I have logged out and in, I have restarted the program, I have reinstalled, I have deleted Lightrom 5. I have restarted my machine.
This does not really help my view on subscription software.
This 'fix' didn't work for me. I signed out and in multiple times, restarted my computer, and now it tells me I have to sign in for an expired trial version. This is crap Adobe!!!!!!!
That Adobe fix of deleting stuff didn't work either. I used the app when I first downloaded it, and now what am I supposed to do to get work done NOW?!!!
Yes, signing in and back out worked, but that should not be required and if it is Adobe should let the user know. Would avoid a lot of time wasted on everyones part.

For those of you who are having problems running lightroom CC 2015 after installing it, and signing out of CC and back in did not work, please see option 2 at this link:
Lightroom doesn't launch or quits automatically after splash screen
Excellent answer works a treat sign out then sign in
I have tried the sign out and sign in - did not work.
Tried the procedure in your post link, renaming the SL Cache folder. I was not able to find a SL Store folder.
Now I get an "Error 16" and the CC app lists LR and PS uploads as trial versions only.
I reset my cache folder back to previous since it was not working.
This really sucks. I, too have signed out of CC and back in, and LR worked for a while, but now it won't even start up again. It makes it really hard to get work done when you're always having to f-around with the software!
I have done everything people have tried above, but LR will still not come up. The only thing I get is a screen that tells me how many days left in my trial, which is now down to 8 days & I have been in once.
I solved this problem by Windows 7 Service Pack 1 update
tomh23423198's tip worked for me.
Have been experiencing this same problem.
I have lightroom installed along with Creative Cloud and it had been working fine for a couple of months.
Two weeks ago it failed to open.
I have tried every solution which has been recommended on this thread including:
Log out and back in to CC.
Delete Contents of SLCache/SLStore folders.
Uninstall CC and Lightroom and Reinstall.
Change Permissions and Security settings of SLStore and Adobe PCD.
Non of the above have worked and Lightroom still will not launch. Frustrated is an understatment given that 1. I am paying for this software and cannot use it and 2. it worked fine untill 2 weeks ago.
Surely Adobe should have resolved this without me having to waist 50+ hours trying to resolve the issue with no success.
Can Adobe please provide a solution? or should i just cancel subscription and ask for a refund before going back to using free photodirector 5
I cannot open up my light room, I signed out and signed back in. It is telling me its already open in another apploication but i cant find it, and it still wont open, I even tried running as an adminsitator
Hummm. I updated (downloaded) via CC 18 hours ago and now LR will not open. PS and BR are okay. I have logged out of CC and logged back in. Restarted my Mac, Powered off my Mac, Logged out again. Still no luck.
Has anyone else found this problem?
The Banner screen opens with a face (blue/green) and the eyes are closed if that helps anyone for the build number.
Thanks in advance for any advice.
I don't know what is going on. But I'm having a similar issue of LR 5.7 not starting.
Click on LR shortcut and nothing. I've shut down and restarted my computer and still Nothing
Attempted a repair of 5.7 - Nothing
Uninstalled and reinstalled 5.7 - nothing
Uninstalled 5.7 and installed 5.7.1 - nothing.
I'm lost as to what to do to make this work.
Any Help would certainly be appreciated since I have a client waiting on their photos.
Signing out and back in to the CC app did not work for me. The only thing that does work is logging out of my user account and then signing back in. I'm on Windows 10 and have the latest version of LRCC installed, including the latest patch.
