I don’t know if this has anything to do with it, but I did have the trial version installed before I tried to install this version.
The trial version said that I needed to uninstall it before I installed the full version of Premiere Pro 2.
Also, I have 1.5 installed right now… but as I understand it, Premier 2 is a parallel install, and shouldn’t have any conflict with 1.5.
At least, that’s the way we have it at work… both 1.5 and 2 on the same comp… and they both work great.
