If You’re Having Lightroom CC Install Issues


Hi Gang:
This is a quick-fix that’s working for many folks who are having install issues with Lightroom CC, and luckily it’s a really easy. Here’s what to do:


STEP ONE: Go to the Creative Cloud App – click on the little Gear icon in the top right corner of window and choose Preferences (as shown above).



STEP TWO: Click the Sign Out button (as shown above).


STEP THREE: Sign right back in and that should fix the problem.

NOTE: Two more things:

(1) You need to sign out/in exactly the way I showed here — from the preferences. Don’t sign out any other way.

(2) You may have to do this sign out/in more than once for it to work.

Hope that helps some folks who are stuck. 🙂



P.S. If that doesn’t work, RC found this discussion on an Apple forum where a commenter gave a solution they say came from Adobe Customer Suport (though we haven’t tried or tested it, and so not sure of the validity of the fix). You’ll see most folks there had their install issue fixed by the simpler method I just shared. Here’s the link.

    Hi, I did the recommended log out and sign in again but accidentally I’ve changed the Install Location in the Crative Cloud preferences. Could you confirm what is the default Install Location that is configured there from before please. Thanks!

    I spent more than an hour trying to do it Adobe’s way (removing temp files and app support files), but this trick worked right off the bat. I can’t believe the problem has been around so long, the fix is so simple and Adobe is so dumb.

    I can’t believe this worked for Lightroom cc 2015.6! I was going out of my mind. Not only would it not update, at some point I lost all prior updates.
    It’s amazing that signing out of adobe fixed it. My next move was to uninstall.

    I have tried the sign out sign in multiple times, with no luck. I uninstalled wiping out the preferences. I went in and renamed the SLStore and SLCache folders. Lightroom sort of works – but I still crash if I click on preferences, which of course, is now an issue since I wiped out my preferences. I use the software in my classes so This is now a major issue. I have already posted on Adobe looking for help. Not sure what else is left to try.

      I spent about 2 hours on chat and phone with an adobe support person. The crash pointed to a DLL that is there for lightroom (according to him) and he removed it. Uninstalled and reinstalled, and got Lightroom working again but now I get the loadlibrary w 126 error in photoshop which points back to that same dll. So the graphics have now been disabled. This is due to some issue with the AMD video driver. Now there is a post on Adobe that says it is a known issue with the AMD Ratheon drivers and it is being worked on. So laptop is now in a tech hands as they try to get the drivers reinstalled. So this upgrade/install has now cost me $$ (and a full day of uninstalling and installing, etc) because of the changes that adobe released before vendors had a matching working version.

    Thank you for this advice, it finally worked and I can start using LR. One thing: After trying it several times with no success I noticed that I had an update waiting to be downloaded – I had previously missed it – and after downloading and installing the ‘log out-log in’ finally worked. Thank you.

    Hi, I´m having an issue with GPU option in LR CC. The video card is a Sapphire Firepro V4900 with the latest drivers installed, and LR gives me an error message. I can´t find the way to correct it.

    Thanks very much for this!!! I was able to install it but when I tried to launch it, nothing happened! I uninstalled lightroom and reinstalled, NOTHING! I did this fix it immediately worked and allowed me to use CC! Thanks again guys.

    THANK YOU! I tried uninstalling and reinstalling adobe cloud, I tried uninstalling lightroom, I tried clearing out all trace of lightroom and still Adobe Cloud only offered my the option to “Try” Lightroom CC. After following the above, it finally lets me install it! THANK YOU!

    I’ve spent hours already on the phone with Adobe Tech Support. My desktop (win 7 64-bit, 16Gb RAM, plenty of HDD space available, drivers updated, etc, etc) simply won’t run the new Creative Cloud desktop app for more than a few minutes. LR CC will open up and work for a just a few minutes before seizing up. Photoshop works only intermittently. Non-Adobe products work just fine. I’ve checked out the usual physical stuff – hard drives, memory tests, cleaned out temp files, etc. Even Adobe says that this system should handle CC just fine.
    But, it doesn’t!! Major disappointment………and huge waste of time and $$.

    Started working on my laptop this morning to try to get something done over the weekend (Adobe tech support doesn’t work weekends – another problem – we’ll start again on Monday afternoon). Now the laptop is balking at LR CC & PS – slooooow.

    Hi Scott, just installed LRCC but now my Photo Mechanic will not launch LRCC – my workflow just took a hit. If you know a fix, please share.

    My Lr CC installed fine the other night, but tonight while trying to edit in the Develop module Lr has crashed several times!!! Anyone experience this and have a fix?

    • Dave 27 April, 2015 at 06:07 Reply

      I have the same issue – 4 crashes in the Develop module within 2 hours after ‘upgrading’ to LR CC. Very frustrating. Another forum post may suggest a graphics OS/driver bug, but nothing conclusive so far and no fixes…

      I’m working on a Macbook Pro (mid-2009).

        Using a 2007 Macbook Pro with NVIDIA GeForce 8600M GT. Lightroom crashed every time I tried to crop an image. Turned off using the graphics processor in preferences, no more crashes.

    If all else fails, delete the preference file. The only safe way to do this is to uninstall LR CC from the Creative Cloud. Reboot. Then reinstall LR CC but when it asks you whether you want to use your existing preferences or delete the existing preference file, choose DELETE. It will regenerate a new preference file for you. While this may be a pain for some, it solved every single problem I had. I looked at the “converted” preference file from the earlier install (undelete files is a handy thing), and the file was complete corrupt. You may be experiencing this problem and deleting the pref file almost assuredly will solve problems that arise INSIDE of LR CC (in my case, extremely slow preview rendering, no histogram, failure to close properly, requiring a “Force Quit” under OS X Yosemite 10.10.3.

    Hope this helps a few people.

      I was curious if you tried deleting the preferences by starting CC with SHIFT-ALT/OPT and clicking on the LR CC icon ? That lets you reset preferences, but ‘haven’t needed it yet and storing it away if needed in future. Thanks.

    Got this same solution from an Adobe tech support guy and it worked, sort of. The program started to load but balked when it tried to load a particular catalog that was being used by another version of Lightroom, according to the error message. However no other Lightroom programs were open. I solved the problem by just choosing another catalog and then everything went fine. After a successful loading, I was free to then load my catalog of choice.

    I’m on Windows 8 and it took four installs and two chats with Adobe Help to be able to launch LRcc. In an attempt to figure out what was making it so slow I found that the program was set to run in Vista (which I have never had). My only other option was to choose Windows 7, but that increased my speed to useable. I’m hoping to find out that there is a Windows 8 setting, but for now I can use the program.

    • Shelly Waldman 6 May, 2015 at 22:51 Reply

      Where did you go to find this setting? I’m having a tough time getting LR to run and wonder if this is part of the issue.

    In Windows try Control Panel – Internet Properties – Connections – LAN settings the set Automatically detect settings and turn off other – click OK
    And then try signing in.

    Hi All,

    So far the only problem I have had is none of my “User templates” show up in the print module, …I have a lot of User templates.

    I could have saved 45 minutes on customer support if I had gotten this yesterday. I am sure this will benefit many others.
    Thanks for helping Adobe users.

    Thanks for trying to help. I’ve tried the sign in=sign out (though preferences) and it is not working. Will profanely wait it out until I can get through the Adobe support.

    For me for some strange reason when using the GPU is much much slower than without it!! I don’t know if my settings are wrong but I had to disable it. Anyone with the same issue? And how to fix it. The main update was speed. And I’m not taking advantage of it.

    • Stephen Cupp 23 April, 2015 at 18:38 Reply

      Try updating your video card drivers. If you are on a mac make sure you have all the OS updates. That’s where new mac drivers come from.

    • Ashley Scott 24 April, 2015 at 00:12 Reply

      The main thing about this update was speed as most of the work as been past over to the GPU. This works on the fact that you have a fairly good graphics card, if you are using a sub-par card then in theory it could actually be slower than allowing the work to be done by the CPU.

    • Elliott 24 April, 2015 at 02:37 Reply

      Yes, my card is compatible and when GPU is enabled it is very slow.
      So much for the speed hype.
      As a CC subscriber, I’m very disappointed and think it’s time to look elsewhere now.

    Here are two problems that I encountered, and here’s what I had to do to fix them:

    When going in the development module, if you’re seeing a blue rectangle with a white X accross, instead of the actual photo, update your graphic card drivers.

    If you calibrate your monitor with an external device (ex: Spyder) and the photos in your filmstrip, the previews and histrogram have a color cast (yellow in my case), run your calibration again.

      After having no trouble with the install on my laptop and a ton of trouble on my desktop I remembered my desktop is a 32 bit OS. I checked the specs on LR CC and it is only for 64 bit systems. Adobe stated they didn’t know when or if it would be ready for 32 bit OS.
      Haven’t seen this problem stated anywhere.

      • lyle 24 April, 2015 at 18:01 Reply


        It’s been widely distributed in may places since the first of the year that it would only be available on 64 bit OS, although you might not have seen it.

        The other issue I’ve had a few emails about are Windows machines which look like they should be supportive with the graphics card, but are not displaying image in Develop module. One may have to go to the graphics card vendor to be sure they have the latest drivers for Windows they’re on; the Windows Update process doesn’t provide updated graphics card drivers all the time. There’s a link to the 3 biggies at the end of a link in Edit | Preferences – Performance tab – I updated my Intel 4600 driver and it all worked. (I’m going to pick up a new graphics card though – this is a good push over the edge to rationalize it finally 🙂 )
