I just found at a workaround, although probably everyone who couldn’t get PP2.0 has upgraded by now (although this program is still great at editing HDV footage).
Install Premiere Pro 2 as normal. Activate, etc. Try launching it for the first time, and you will see the splash screen and then it will disappear.
NOW, navigate to C:\Program Files (x86)\Adobe, locate the folder named Adobe Premiere Pro 2.0. Right click on this folder, choose copy, then go to your Windows desktop, and choose paste. Wait patiently while it copies everything. Once the copy is done, go into the Adobe Premiere Pro 2.0 on the desktop (not the one in program files), and double click on the Adobe Premier Pro executable. The program should launch and run as normal. Running it under XP compatibility may make it run smoother, but I don’t think this is required.
I discovered this fix after hours constantly trying various re-installs. After I while I realized it was a permission issue with the program files folder. Because YOU own the permissions to the Desktop, the permissions issue disappears.
Hopefully this helps someone other than me 🙂
