Thank you!I'd be surprised if you didn't have .Net Framework in Windows 7 Home Premium. Uninstall your Pinnacle product completely, and then clear its remnants:

Now try installing it again. Pinnacle support forums can tell you more on this issue.
Downloaded on ran it. It found the Pinnacle plugins (which I knew were there), and removed them.
I then re-checked for 'pinnacle' in revo but it found nothing.
Sadly, when I re-tried Pinnacle install, it came up with the same failure as before:
"Requires .Net Framework 2.0...."
Will try looking in Pinnacle fora. when I can find them.
