Lightroom gives "An error occurred when attempting to change modules." message when opening

I am attempting to get either LR 4.4.1 or LR CC to work on my computer but continually get the message posted above. I have tried both LR 4 and CC (deleted and re-installed several times) and neither seems to work regardless of what I do. I have tried the help page which includes: changing permissions, re-installing, removing the preference file (com.adobe.Lightroom4.plist), and more.

I am running OSX 10.8.5. Attempted both as "trial" versions.

Are there any other steps I can try or that I missed? I really want to purchase this program but unless I need to know if it's compatible, so far it's not looking good.

Well since you can't purchase 4.4.1 any longer, you might consider trying the trial of LR 5.x

LR CC would mean LR 5.x via CC.

There is a procedure for fixing LR 5.5 when it gives an error about needing to be reauthorized, so maybe the error is slightly different during the trial period and the following procedure involving deleting the contents of the SLCache folder but not the folder, itself, that fixes things, so you might try it:

LR 5 is what I currently have being attempted (via CC). I will give that link a try and get back to you.

Hi Steve, I just attempted clearing the Cache as well yet I am still getting the same message. Not sure what my next move should be at this point.

You could uninstall everything Adobe-related and run the CS Cleaner and start over and see if things work any better the second time. I'm not sure if the CS Cleaner affects LR things, but it may at least do something with the Creative Cloud app from Adobe in case it has something set wrong:

Since you are just trying to trial the software, you could attempt to install the standalone version and perhaps a slightly older version, LR 5.4 or 5.3, from this page: http://www.adobe.com/downloads/updates

You might also try Adobe Customer Support which is what you get links to (at least in the US) after you've jumped through the hoops to tell the website what area the problem is in and then choose the Still Need Help option, which should reveal a chat and phone and a community option, I think.

I tried the CS Cleaner the other day but perhaps I missed a step in that. I'm almost just tempted to jump right to purchase but I just have a feeling it won't resolve the issue and I'll be stuck with a bill and a useless program. Maybe Adobe Support is best at this point because I even tried a back-dated version as you suggested the other day as well.

Purchasing won't change how the program works, it'll just license it so it won't expire after 30 days.
