"error occurred when attempting to change modules" ...Troubleshooting didn't work

Just downloaded Lightroom 5 on my Mac and received the above message. I tried each step of the troubleshooting page but it still isn't working.  Any other ideas?

As of this morning I have updated to OSX10.9.3 and iTunes11.2.1.  I uninstalled, reinstalled, and got the same message so I went through the troubleshooting procedure again.  No luck.

  • 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.

  • Error occurred when attempting to change modules in LR - just purchased and opened for first time

    I just purchased and downloaded the monthly subscription to LR 5 on my new iMac. When I open LR it displays an error message that says "An error occurred when attempting to change modules." I cannot import anything. I'm stuck and very frustrated. I just paid for this monthly service and am stuck for a year. Please help me troubleshoot this problem. I've uninstalled and reinstalled several times as well as restarted my iMac.

    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!

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

    I'm a first time Lightroom(via the Cloud) user (used Capture One before this) and just downloaded it today. The first thing I saw was this error message
    "An error occurred when attempting to change modules."
    I've updated it to 4.3 and I've tried all the other recommendations I found here:
    http://helpx.adobe.com/lightroom/kb/error-changing-modules-lightroom.html
    I don't know what Nik products are but I don't believe I have any.
    I'm on a Mac running 10.6.8
    Removed this preference file I found here:
    http://helpx.adobe.com/lightroom/kb/preference-file-locations-lightroom-4.html
    So frustrating! Please, can anyone help me???

    I can only quote from the webpage that you already visited RE: Permission.
    You need to have full permission for reading and writing for the folders and drives that Lr is using - particularly the folder that contains the catalog (i.e. the database Lr is working with).
    If you have full permission try re-installing Lr. Un-install it via your OS. And re-install it.
    Also, occasionally downloaded programs can become damaged during download - for instance when the download has been interrupted.
    Before you re-install, I'd recommend that you download Lr again and use this second download for re-installation.
    From the webpage (particularly read the part about Macs):
    Solution 5: Set correct permissions on Lightroom folder inside Application Support  
    The Lightroom folder inside Application Support could have the wrong permissions preventing Lightroom from writing to it which can cause this error.
    Navigate to the following folder: /Users/[user name]/Library/Application Support/Adobe/Lightroom
    Highlight the Lightroom folder and chose File > Get Information
    Under Sharing & Permission, verify that your have Read & Write Privileges. If not, click the padlock icon at the lower right, enter your password when prompted, then click the Read only entry and select Read & Write.
      Important: (Mac OS) Apple made the user library folder hidden by default with the release of Mac OS X 10.7. If you need access to files in the hidden library folder to perform Adobe-related troubleshooting, see How to access hidden user library files.
    Solution 6: Try a different user account.
    Copy the Lightroom folder into a new user account or other existing account on your computer. Then, restart Lightroom. The Lightroom folder is in the following locations:
    Windows XP: C:\Documents and Settings\[user name]\Application Data\Adobe\
    Windows 7, Vista: [user name]\AppData\Roaming\Adobe\
    Mac OS: [user name]/Library/Application Support/Adobe/
    Important: (Mac OS) Apple made the user library folder hidden by default with the release of Mac OS X 10.7. If you need access to files in the hidden library folder to perform Adobe-related troubleshooting, see How to access hidden user library files.

  • 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.

  • 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)
