I don't think PRE 5.1 will work on Win 7, be it 32 bit or 64 bit as it was never tested on Win 7. Also, so far we only have 64 bit version for PRE 10, not for previous versions.
So, you can try rebooting the machine or turning off UAC and perform selective sartup and check if that helps.
Better option is to upgrade to PRE 10.

If you have Win7 64bit PRO or higher, try Microsoft's Virtual XP
This is only ONE example of using Virtual XP http://forums.adobe.com/thread/702693
Welcome to the forum.
There was no Premiere Elements 5.1. PrE skipped from version 4 to 7, to align its version numbers with those of Photoshop Elements.
Now, there was a PrPro CS 5, and I believe that it was updated to 5.1 (maybe 5.0.1?) PrPro, as of CS 5 is a 64-bit OS version only.
Exactly which version of which program do you have?
Excuse my confusion - it's Premiere 5.1
That would probably be a better question for the Premiere forum.
Although Premiere 5 is nearly 15 years old. I'm suriprised it even runs on Windows 7 at all!
Got you, and thanks for that clarification. You want the Premiere - Premiere Pro CS4 & Earlier Forum. Not sure of the answer, but someone there can help you.

I upgraded a Vista 32-bit to Win 7 64-bit and now cannot seem to install. A message indicates I should check the 32-bit or 64-bit compatability.
Thanks for any assistance.
You will not be able to install Premiere 5.1 (quite an oldy) on a 64 bits machine.
5.1 is only 32 bits.
Back to what I wrote in #2 - which version of Windows 64bit do you have?
Windows 7 64-bit
Do you have the Home or Pro or Ultimate version?
If you have Pro or Ultimate, go back and re-read my reply in message #2 - the process for Pro/Ultimate MAY work for you
Premiere Pro 1.5.1 worked that way with a i7 64 BIT, no issues, and so does Premiere Elements 4 , still working on a Pentium 4 Pro XP ...,and fast on the i7 64 bit, but, I have now gone to CS5.5.2
