Lightroom 5, can't open..an error occurred when changing modules

I got Lightroom 4 with a new camera.  couldn't install on my Mac so purchased  (full price) lightroom 5.   Retrieved my key and downloaded and installed on the Mac.  Lightroom is there, but when I try to open in says "an error occurred when changing modules".  I have uninstalled and reinstalled several times.  Went online and tried some suggestions but nothing works.  I have had no problems running or using LR5 on my PC.  I really like the program...I don't know what to do next. Running OS X 10.9.2.

  • I am unable to open another Firefox4 window when I have the Error Console open and I can't open the Error Console when I have two Firefox4 windows open. Is anyone else having this problem?

    I am trying to debug the jQuery to a micro site I've created and I am unable to open the Error Console when I have two Firefox windows open and I am unable to open a second Firefox window when I have the Error Console open.

    I personally haven't experienced much of the "reverberation/feedback" when using a headset on the i4S...
    Yes, I have near-perfect hearing too (for scope, squeaky brakes hurt my ears) I come from many conversations on many phones and types and first off, CDMA technology is great for coverage, terrible for voice quality. HD Voice in Europe made for some of the best phone conversations I've ever had.
    Back on track, feedback is most noticable (similar to the landline phone) when using the iPhone without a headset, but for me it's not an absolute criticality mainly because I use VoIP apps alot, so maybe it has desensitized me some over the past year.
    But whenever I'm on a call, and the other person has me on speakerphone, I have alot of trouble talking because of the feedback loop caused. So the less of my voice I hear the better I can talk.
    Have you tried a bluetooth headset yet?

  • Error has occurred when changing modules

    Hi, I have just recently downloaded lightroom and I am receiving that error. Before someone sends me this link- I've already tried it and nothing worked.
    I'm working on a Mac running OS X Yosemite 10.10.2. I originally tried doing the trial from CC but it gave me that error so I tried installing my Lightroom 5 and it did the same thing. It's a new laptop so I had to put all my Adobe back on which is why this is a new issue for me.
    Thanks

    Please just say how you removed the CC version and did you remove the Preferences from Hidden User>Library??

  • Photoshop CS3 doesn't open or error occurs, when you Edit in Photoshop CS3 from Photoshop Lightroom 2

    Problem: When you try to Edit in Photoshop CS3 from Adobe Photoshop Lightroom 2, Photoshop CS3 doesn't open, or after Photoshop opens, you see the error message, "Photoshop could not be launched".
    This issue is currently being investigated. At present, there are two possible areas that might be causing this issue. Corrupted metadata or a corrupted catalog, or Photoshop CS3 has not been updated to 10.0.1, or the update did not apply correctly to the application.
    We are working for a permanent solution for this issue.
    Workaround: Please refer to this Adobe
    TechNote for further information.

  • Error Message:  an error occurred when attempting to change modules

    I have seen the link that addresses this problem.  Lightroom is updated.  I uninstalled Photomax.  But the problem with Lightroom continues.

    I have this same problem... clean install of the Lightroom trial on Leopard.
    By clean, I mean it has not previously been installed- and after install the attempt to open the application results in the popup message about errors occuring when changing modules...
    Once "Ok" is clicked the program completes load with a 'blank' screen..
    In addition, the Program preferences panel will not load-
    any attempt to access a module results in the error message be again presented.
    I would hope the Adobe would give this some attention, can't expect to sell me on the app- if I can't get the trial to run?!/

  • 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.

  • ???  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.
