I installed Lightroom 5.6 on Mac, when starting I receive an error message "An error occurred while attempting to change modules"

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.

  • "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.
    Error changing modules | Lightroom
    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.

    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:

  • 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 and I cannot go any further. Can anyone help?

    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.

  • "An error occurred while attempting to change modules" message occurs whenever I try to run Lightroom. Can't use it. Can anyone give me any hint to solve the problem?

    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.

  • I want to install lightroom previously installed on a macbook on a new macbook. I get an error message when I try to use the same serial number. How can I install lightroom on my new mac?

    Oliver,
    Are you getting activation errors? As Ned stated , it is easier to troubleshoot if we have the specific type of error and error detail that you are getting.
    Here is some help on activation if this is the issue:

  • ???  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 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.

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

    Lightroom 5.2 on a Mac....keeps saying 'An error occurred when attempting to change modules.

    I FIGURED OUT HOW TO FIX THIS PROBLEM!
    i\IIf you get the error message, “An error occurred when attempting to change modules” open up a brand new user account on your computer, name it something (Do not use Guest). Lightroom will be installed on both users, however everyone wants it to work on their main account, here is how you do it.
    Click on the go menu at the top of the desktop in the new user profile and hold down option or the alt key. A tab will pop up that reads library. Click on it. A finder will appear, look for application support and click on it. Next, click adobe folder in Application Support and scroll down to Lightroom  Copy this folder and paste it into the main user. HOW TO DO THIS? First copy the entire folder and then click computer in the go menu, Macintosh HD and then Users. Find your primary user account. In this case it would NOT be the one that looks like the house because you are on your alternative account! Nevertheless, find your main user account, click it and paste Lightroom folder into it. Doesn’t matter where you paste it, just know where it is.
    NOW, log out of the alternative account and log into your primary user account and find the copied lightroom folder. Do the same thing mentioned above, Go menu, Computer, Macintosh HD, Users, but this time click the house tab. Find where you pasted the folder and paste it back in application support in the library via go menu. It will ask you to replace it. Hit yes. If it does not allow you to. Click get info on application support tab and make sure everyone is on read and write. Once pasted and replaced start up Lightroom.
    IF NOTHING HAS WORKED FOR YOU DO THIS METHOD, IT WORKS!!

  • 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?

    Best guess is a permissions problem although you haven't mentioned what operating system you are using.
