I have a serial number that I purchased. I thought you could install it on both a desktop computer and a laptop. It works fine on my desktop. When I tried to put it on my laptop, I enter the code, click next and wether I enter registration info or not and click finish, Lightroom just closes and when you try to open it again it goes back to the "you have 0 days left on your trial, purchase or buy" window. First I completely uninstalled Lightroom and re-downloaded it. Got the same thing. So then I figured it was because I couldn't download it on my laptop so I got ANOTHER copy from from the school I teach at. Its doing the same thing!?! What gives? I just want to use Lightroom on my laptop! Please help! THANKS!
I have also tried checking the permissions, checked to make sure I was in an admin account and tried doing what this article said. http://kb2.adobe.com/cps/401/kb401346.html ..... still no luck.
