Adobe released the official non-beta version of Lightroom 2 today. It would appear that they still have not resolved the problem where Lightroom says, "An Error Occurred While Attempting to Change Modules." I would think Adobe would pay attention to the complaints of many users who have experienced this problem but their recommendations sure haven’t worked for me and a handful of others. Some people suggest totally removing all references to Adobe Lightroom and Photoshop. Others recommend removing the Lightroom catalog. I would love to use this program if Adobe could work out the bugs… If you are thinking about getting Lightroom, I’d recommend jumping over to Adobe’s site and downloading the trial before you actually drop $299 on it.

I think this problem is fixed in 2.1 (you can try the RC from Adobe Labs’ site). I think it has something to do with your preferences file; I’ve been able to fix it every time by just deleting my lightroom preference file. For me, I think it gets messed up because I sync preferences between multiple machines, but I’m not sure about that.
Anyway, though, try deleting your Lightroom preferences, and it might just come right up. Or try downloading the 2.1 release candidate, if you’re so inclined…

Hey Greg, I have tried both of those things – no luck. I saw a post online somewhere where a guy said that had to create a second user on his Apple and do an install on that user. He then copied all the install files to his other user account. Apparently there is a problem where Lightroom doesn’t always install all the files properly. I intend to give it a try but I haven’t had time lately.

Agreed. I have tried everything when it comes to downloading this program- Nothing stops this error msg.
