• After downgrading to Lightroom CC 2015.2 CC 2015.1 LR start error message "an error has occurred when attempting to change modules."

  Had problems on OS X Yosemite 10.10.5 with Lightroom CC 2015.2 suspended several times so followed the advice on the forums:

  - uncheck "Show"Add Photos"screen" "

  After awhile the same day LR would always hang and now totally crash at startup with no error messages or anything like that. Tracking guides:

  -Sign out, then back in CC

  -Deleted preferences of Lightroom with Option + shift while clicking on the application icon

  -Preferences from LR deleted via Finder

  Has not set, LR has not yet started. Decided to downgrade following guide how roll back to Lightroom 6.1.1 or CC 2015.1 | Lightroom training Laura shoe, tutorials and tips from:

  -Uninstalled CC 2015.2

  -Reinstalled old CC 2015

  Does not solve the problem. Lightroom said: "an error occurred when attempting to change modules." and the catalogue has not loaded. Then followed guides:

  -Creation of a new user account and trying to open Lightroom it

  Does not work, did not start there either, same error message. Decided to try to uninstall and reinstall the old CC 2015 once again, this time turn off the computer laptop inbetween:

  -Uninstalled old CC 2015

  -Disconnect from CC

  -Restarted MacBook Pro

  -Connect to CC

  -Installed new old CC 2015

  Always the same error message "an error has occurred when attempting to change modules." and can not use LR. Following following guide https://helpx.adobe.com/lightroom/kb/unable-launch-lightroom-55.html:

  -Disconnect from CC

  -Rename the files SLCache > SLCacheold and SLStore > SLStoreold

  -Open LR and connected to CC

  Always the same error message "an error has occurred when attempting to change modules." and cannot do anything with LR.

  
  

  Now I don't know what to do anymore. Help, please.

• 6.6 Lightroom, that an error has occurred when attempting to change modules

  Whenever catalogs of switching or create a new catalog in Lightroom 6.6 I get the error 'an error occurred when attempting to change modules' bit followed by a crash of Lightroom. I followed all the steps in the troubleshooting guide for errors that can occur when you change the modules in Lightroom repeatedly, wiping out all my settings and the catalogs and re - download Lightroom from Adobe web site and put it back, all to nothing does not, the problem persists.

  When reinstalling, I noticed that Lightroom 6.0 doesn't have this problem for me. However, once upgraded to 6.6, it presents this crash. On a lark, I tried upgrading 6.0 only to 6.5.1 - it works and allows me to create new catalogs without crashing. So, it seems that any accident that happens here recently got introduced to 6.6.

  I use a 2010 Mac Pro running MacOS 10.11.5.

  Are there solutions to this crash to 6.6?

  Look here for a solution.

• Lightroom 4: cannot change to slide show Module - Get error has occurred when attempting to change the module

  I have a new MacMini (2 months) with OSX 10.8.2 and 16 GB of ram. I had a partial re - installed, bringing more of my settings from my old computer (a MacBook Pro, 10.8.2)

  4.3 Lightroom worked very well until I went to use the slideshow module.  I received an error message and the library module does not open.  Read the message "an error has occurred when attempting to change modules.

  What can I do to fix this?

  Here's what I've done so far:

  1. checekd the disk permissions and disk status - all ok
  2. check the integrity of my catalogs and saved them - all ok
  3. moved files preferably, ending with 'plist' from the root and user libraries - no change
  4. only moved to the folder of the user, to support / library/application - no change
  5. Checked and opened upward "privileges" on the files for the library files and the catalog files.  Checked 'apply to all files' - no change
  6. contacted one and Nik to see if they had heard of this problem - no, they didn't and don't think their programs could be the cause of this problem
  7. Contact Adobe - level 1 support - crossed some of the points above - no effect

  I am waiting for a call from level 2 return to Adobe.  In the meantime, one has this problem or have any other suggestions.  The only alternative I have is to completely uninstall Lr and start again.  But it's a bit drastic.

  Thank you

  This is a bug, usually related to having a second monitor attached.

  Roll to 4.2 from here: http://www.adobe.com/support/downloads/detail.jsp?ftpID=5487 - simply drag 4.3 to the trash, and run this installer.

• Lightroom: "an error occurred when attempting to change modules."

  I am a user of Lightroom (via the Cloud) first time (used Capture One before that) and just downloaded today. The first thing I saw was this error message

  "An error occurred when attempting to change modules."

  I've updated 4.3 and I tried all the other recommendations, I found here:

  http://helpx.Adobe.com/Lightroom/KB/error-changing-modules-Lightroom.html

  I don't know what are the products of Nik but I don't think I have.

  Deleted this file, preferably, I found here:

  So frustrating! Please, can someone help me?

  There was an old Installer bug which could be related.  If it works in own account, copy the files back may work.

  Save your copies of the following files/folders from your user account and then copy backup versions of the proprietary.

• An error occurred when attempting to change modules. 5.2 on Mac Lightroom

  5.2 Lightroom on a Mac... keeps saying "an error occurred when attempting to change modules.

  Pilot78 I have a solution for you!

  Go to the following folder: /Users/ [user name] / Library/Application Support/Adobe/Lightroom

  Then press control, click the lock icon, go to permissions, do read and write access to all.

  For me, which did the trick. Stupid that Adobe didn't help me on the phone with this, the support rep was actually rather rough.

  Hope this helps
