Can anyone help?
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).

Down loaded lightroom 5 and installed but won't open right. On opening Message "an error occurred when attempting to change modules"

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?

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.

Downloaded a trial Lightroom and got "An error occurred when attempting to change modules." Macintosh. Created another user and it works. WIll this happen if I make a full purchase? I want to use my administrator user.

This might be due to incorrect preferences / permissions issue on the Mac.

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.

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