An error occurred while attempting to change modules
I installed Lightroom and when starting the program I get, "An error occurred while attempting to change modules." I get this message within the program when clicking on any of the top right menu items. Also, importing a photo is not listed in the file menu. I deleted the preference file and Lightroom folder in my user preference and reinstalled. I tried many reinstalls, it still has reoccurring error message. Anyone now a fix? I'm running 10.5 on a Core Duo with 2meg of RAM on a 320 gig hard drive with lots of room.
For what it is worth, I was unable to change to the Web and Print modules, and I was also unable to record new presets (though I had successfully done it many times before) though I could still use already created ones. I was baffled, but found a workaround using hints from this and other forums. Much thanks to those who provided me with a starting point as I never would have figured this out on my own.
My wife is a separate user on the same computer, and I tried switching our catalogues and preference files, ... nada. Looking at her folder structure under user/library/application support/adobe/lightroom, she had folders for Web Templates, Web Galleries, and Print Templates but I didn't. So, simply copying her folders (not creating new ones of the same name, which may still have worked) into my own lightroom directory worked.
Where I screwed up initially was tryiong to use my own presets under her install of lightroom and then creating new ones (which worked) but then trying to import them back into mine. I had the new presets working under my own install, but still couldn't create new ones under my own setup. Finally, I realized that it was the "Develop Presets" folder under my own install that was in some way corrupted and copied her Develop Presets folder into my own install and every thing was fixed. I could even copy the subfolders from my own Develop Presets folder directly back in without issue.
Hope this helps someone. -
"an error occurred while attempting to change modules" when launching lightroom
I get the message "an error occurred while attempting to change modules" when I launch the app on my mac.
Every other adobe app works like Photoshop
I have followed all the troubling shooting steps in the link below, not one of them makes anything different. Except I tried the last one. I created a new account, simply logged in and launched the app and everything ran normally. No problem. However it doesn't say what to do if that works it just says try it.

Obviously this means its going to be an issue with a support file in the one user account but what one?
I also can't un install lightroom either, when I go to the creative cloud plug in on my menu bar the uninstall says its unavailable but the others are fine.
Any ideas?I just found the answer for me.
I did step 5 on this support article:

I installed Lightroom 5.6 (full version, not trial) on Mac, when starting I receive an error message "An error occurred while attempting to change modules".
I tried removing it and reinstalling but the same error comes up.
Anybody have any recommendations?A forum thread from 3 years ago talking about LR 1.x which had this problem seems to need permissions fixed or new folders created with the corrected permissions. You might try doing a repair permissions for your user and/or run LR as an administrator user. I am a PC person so cannot tell you exactly how to do that.

Despite it is claimed in Adobe forum that Lightroom is fully compatible with OS Maverics on my MacBook Air IT IS NOT. A message "an error occurred while attempting to change modules" appears every time I try to open Lightroom. This happened immediately after upgrading to Mavericks. On my doughter's same machine Lightroom works perfectly. Can anyone help?
Surely the Adobe forums are the place for help with Adobe applications. The fact that the problem doesn't occur on your daughter's machine suggests that it's not an issue with Mavericks but a local problem on your own machine.

Just a guess, but since everything is new, perhaps you have some sort of permissions problem.
Make sure your user has write access to all the locations mentioned in this link:

This is a new MacBook with a new CC LR5 installation. There is however no menu choice allowing me to import photos. Np right or left panels at all. When the program opens I get an error message saying there was an error changing modules.
I Nearly bought from Amazon too but I found a thread from Adobe stating that the only recognized outlet for lightoom is themselves and other outlets serial numbers will not be guaranteed.
THat at was sufficient for me to buy direct from Adobe, hope you get it sorted. -
I found a solution in one of Apple forums. I will copy her post:
" I was checking the differences between my normal admin User account/Library/Application Support/Adobe/Lightroom contents and the one on the clean other admin User folder in the same place on the G4 PB where Lightroom2 had launched normally and noticed that on the one that works there are a slew of folders (Develop Presets, Export Presets, External Editor Presets, Filename Templates, Filter Presets, etc etc). On the main admin account, there was only one, the first. So it seemed the install on that account didn't load all the needed info. I simply copied the missing folders from the account that worked into the Public folder, switched to my main account and added those missing folders in the proper place. Voilà!. Now Lightroom launches normally and I don't get the dreaded missing modules alert."
The problem with me is that I do not have a working copy of Lightroom, just 1 account in which it doesn't run and don't know where to copy the missing folders from. Please send some advice.Surely the Adobe forums are the place for help with Adobe applications.

I just installed Lightroom 5 from Amazon for my Mac with 10.10.1 software. When I open it I get: "An error occurred when attempting to change modules". It won't import photos and has no side panels under Library. What should I do?

I have Lightroom 5 installed on my iMac which I downloaded (uploaded?) to my MacBook Air (via wi-fi) but unlike the iMac, I'm unable to use the program on the MacBook Air. When I open the program on the iMac and click 'file', (as people using the program would know) there are 21 options - import pics, export, etc, etc - however, in the version on the MacBook Air, opening 'file' gives me four options - New Catalogue, Open Catalogue, Page Setup and Printer - and with that comes the pop-up message "An error occurred when attempting to change modules". Any ideas please?

Encountered an error when attempting to open Lightroom for the first time. Went to Lightroom Help and searched for the error "An error occurred when attempting to change modules". Non of the solutions helped. What now?
I am getting this error message as well. I have just downloaded Lightroom recently. I try to click on Lightroom / preferences....and nothing happens. I tried to uninstall and it is greyed out so I can't do that either. Suggestions? Please help?

Lightroom trial doesn't show complete menu selections or import button. Also get error message on launch: An error occurred when attempting to change modules. I am unable to find/see the following file to try renaming the SLCache and SLStore files: System Library/Application Support/Adobe. Any ideas? I only have 16 days left on the trial and have been unable to get it to work on my Macbook Pro. This is all I am seeing after Lightroom opens. Thanks!
Thanks to both of you for attempting to help. I finally figured out what was wrong . . . it was a Permissions problem. Very frustrating, but after scouring the troubleshooting tips I finally found the one that solved my problem. I had to add a User and give it Read/Write privileges to Lightroom. The file I had to add the User to was Hidden on my Mac, so that added an even bigger challenge to the mystery. Only a few days left on my trial version! I hope I have time to try it out!
