An error occurred when attempting to change modules.

Loaded LR on my iMac, tried to copy & use a catalogue from W7 P/C. Now get "An error occurred when attempting to change modules."  when opening LR. Tried a variety of on-line suggestions, HELP. NB too much hassle with all the other apps to start a new user with such as Adobe and Microsoft.

Hi, I¹ve been through it again to ensure I¹ve not forgot things. Completely
removed Lightroom and all files I can find, etc and reloaded. Some tedious
result. Step 6 is too time consuming at the moment for me, too many things
on the go since I¹m about to go on holiday and on return I shall need
Lightroom on this iMac. Any clues? This iMac had Mavericks from new,
uploaded to Yosemite and then loaded Photoshop CC, Lightroom etc and get
this damned problem.
Reading around the web I¹m not the only one with this issue, to suggest a
new user a/c is a soft option without resolving the issue.
I hope an expert from Adobe can resolve this,
Regards, George (retired IT Manager and IT Systems Project Manager)

  • Another "An error occurred when attempting to change modules" error

    Hello all:
    After using Adobe Photoshop Lightroom on Mac OSX trouble free for the past 6 months, I opened up Lightroom today and received the following error: "An error occurred when attempting to change modules." I had not made any changes in between when it worked normally and when the error started to occur. I beleive the last thing I did before this error occurred was to go into the Print Module.
    Other information--I keep all my RAW .NEF files on an external Firewire (800) 750 GB drive. This is on Mac OS X 10.5 running Adobe Photoshop Lightroom 1.3 and also with 1.4.1. I'm running an iMac 20" with dual-core 2.2 Ghz Intel processors and 4 GB of RAM. I have around 25k images total.
    When I noticed this problem, I was on Lightroom 1.3. I immediately upgraded to 1.4.1, which did not solve the problem. I have also tried many suggestions in the forums including uninstalling the application and removing the .plist file.
    I thought I had come up with a solution by creating a new catalog, then importing the former into it. While this seems to work immediately after the import process, as soon as I close it, the problem manifests itself again.
    More details that may or (likely) may not help:
    - Going to the Develop and Print Modules gives me no problems. However, when I click on Library, Slideshow, or Web, I see the error.
    - I upgraded my Mac to the latest patch level after observing this error to no avail.
    So it looks like my choices are to create a new file and reimport every single time, or lose all of the work I've done for the past 6 months on thousands of images.
    Can anyone please help???? I promise to post the solution when we fix this darn thing so others may benefit. I'd be happy to run through any troubleshooting that y'all would suggest outside of switching to a Canon.
    Thanks!!!!
    Matt

    I'd first check for the existence of a file ending in .lock, which should be present when LR is in use, but if it exists when LR is quit, it can cause problems, and should be deleted.
    Please post back your results.

  • 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.

  • Lightroom 4: An error occurred when attempting to change modules.

    I downloaded Lightroom 4 a few days ago and installed it on my MacBook Pro. Everything worked great. I thought it would overwrite Lightroom 3, but it didn't. So Lightroom 3 is still installed, but I haven't opened it since I installed Lightroom 4.
    I downloaded Lightroom 4.3 this morning and installed it on the same MacBook Pro.  Using my MacBook Pro and a second monitor, I opened Lightroom 4.3 and worked on some photos. Everything worked great.
    Then I began watching a slideshow in the Lightroom 4.3 slideshow module on the second monitor with my MacBook Pro in the library module. During the slideshow I clicked on the slideshow module on my MacBook Pro and got this error message:
    An error occurred when attempting to change modules.
    Now I can’t get into the slideshow module. I just get the error message.
    I moved the preferences file to the trash and reopened Lightroom 4 but lost color labels, so I put it back in the preferences folder.
    Thanks for your help

    I called Adobe and let them fiddle online with Lightroom on my MacBook Pro. The Adobe tech claims I have a corrupt permissions file. He told me to contact Apple and have them rebuild my permissions file.
    When I contacted Apple, the tech said to startup my MackBook Pro with the option key held down until the first screen appears. Then click on: Recovery HD, arrow, Language, Disk Utility, Macintosh HD, Repair Disk Permissions.
    I did this three times, but some permissions were not repaired. Another Apple tech then suggested I bring my MackBook Pro to a Macintosh authorized repair shop, and have them repair my permissions file. I asked if I can buy Norton Utilities or a similar program and do it myself. The Apple tech said yes, but an authorized repair person will know which permissions to repair and which ones not to touch.
    Unless someone on this forum can tell me how to do this repair myself, I’ll get it repaired next week. And, I’ll post the results as soon as I can.

  • An error occurred when attempting to change modules Lightroom 5 CC

    I've seen other users pose this question but haven't seen any solutions that work for me.  I get the error: "An error occurred when attempting to change modules" when I open up Lightroom 5 on one user, but on another user it opens up fine.  I've tried moving and trashing preferences, uninstalling and reinstalling the program.  It's the same whether I open an existing catalog or try to open Lightroom while creating a new project.  Any help would be greatly appreciated.  This occured after updating to Mavericks on a 2011 iMac.  All other Creative Cloud apps seem to have installed just fine.

    Hi 99jon,
    Many thanks for that. Had been going through this list yesterday and now again today:
    Ref  Solution 1: Lightroom is at its latest update
    Ref  Solution 2: It's interesting how I cannot find the Preferences file anywhere on my mac. (new mac pro, OS 10/9.2) . . .
    Ref  Solution 3: Lightroom doesn't allow me to do anything after the error message appears
    Ref  Solution 4: don't have any Nik Software plug-ins
    Ref  Solution 5: checked permissions and changed all to "Read & Write" - makes no difference
    Ref  Solution 6: I don't have a different user account on my mac.
    Not sure what else to 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.

    For such a big company .. there isn't any chat option to get to someone to talk to  !!!

    Just because you are the only user on the computer doesn't mean you are the administrator.
    Also, the fact that you are being asked to re-enter your serial number each time you start means that it is not being remembered because something is either preventing it from being written to you disk or (less likely) something is erasing it. This does suggest that you lack certain permissions to make changes to your computer. Not only to save your serial number, but to have access to the Lightroom files needed to change modules (they are just plug-ins within Lightroom).
    Try creating a new user account and run Lightroom from there (making sure that it is part of the Administrator group).
    To get to chat support, you have to choose the options:

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