I have Lightroom 5 installed on my MacBook Air but when I try to open the program I receive the message "An error occurred when attempting to change modules". I uninstalled, emptied trash and re-installed but I continue to get the same message.
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?
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.

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.

"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:
Troubleshoot unexpected behavior | User account-specific | Adobe software | Mac OS
It is to repair the permissions on the hidden Library folders. -
Installed CC trial and opened LR, panels on left and right not appearing. keep getting an error message "an error occured while attempting to change modules" plus no import/export options.

An error occurred while attempting to change modules while starting up LR 4.1. New install on a new MBP first time trying to start up
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:

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. 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.

if anyone has any ideas to why this is happening I would love your help.
I fixed the problem myself, no response in chat nor phone (1 hour in hold an no answer) here's the link, step # 5 saved me! Here's the link seems to be a very common problem, hope it works for you! Error changing modules | Lightroom

Have a Mac Book Air with Lightroom 4 Full Download aboard. Just got an iMac. Wanted to load Lightroom 4 on iMac. Took the Adobe download file off the Mac Air and tried to load it on the iMac. It was successfull but on opening the message "an error occurred when attempting to change modules" appeared. I removed Lightroom 4 and went to Adobe orders and re-downloaded my original order to the iMac. Same effect. Bought full Lightroom 5 hoping to fix but the same message appeared. What's up! Any help?

Help, I had aperture open and working on a image and did not have a battery in and bumped the power off. As a result it will not open my master, it is locked. when I try to open that Library it says There was an error opening the database for the library. I have tried every thing. I updated the other libr but now it will not open the main to update. What do I do?
Try starting Aperture with the command and option keys held down. You'll get 3 options.
Try each, starting at the top, in order, checking after each to see if it fixes the issue. -

Probably you have never experienced this, but I have lost the ability to iMessage.
When I try to turn on iMessage, it tells me that "an error occurred while trying to turn on iMessage."
It's not a huge deal, but people with iPhones can't text me back unless they try to re-send after finding out that their message wasn't delivered.
Help!
I think I have gone through every support option available, short of
Scheduling an appointment at the Genius Bar. But I have been to the store three times in the last three weeks.
To solve a different problem, the folks at the store replaced my iPhone 4S.
I came home and loaded my backup onto the new phone. Everything EXCEPT iMessage seems to be working great.
I would really appreciate any feedback...Help!

I own 5. And I own 6. But when I try to open 6 am being prompted for my subscription info.Otherwise am locked out. When I ask for support I get referred to a forum. Remember, two licenses. Oh and since I started the project in 5, It's repeatedly failed to manually save, the audio just disappears, it loses the program monitor, fails to save renders, timecode window burn doesn't work, and that's just for starters.
Thanks Adobe.
What makes you people think this is acceptable?If you have the serial number version of CS6, and you have ever had even a Cloud trial installed... read Cloud takes over https://forums.adobe.com/thread/1584746
