You could check the Adobe forums.
One post mentions it isn't compatible, but without elaboration (which
makes the statement useless, unless we know where the info came from).
(Some kind of sound issue.)

And in this forum, it seems someone got it to work, by using
"compatibility mode" for the executable. There is also the possibility
of doing an Anytime Upgrade if necessary, so you can run WinXP Mode and
run Premiere inside a virtual machine (32 bit).

And compatibility mode didn't work for this person. Gets
stuck at GPUPagecurl.aex .

"It will install and activate, but you won't be able to get it running
enough to deactivate it so you can load the software on another
computer.
If it hangs you can remove 3 Plug ins from the Premeire plug ins folder
that seem to make it freeze. These plug ins are GPUPageCurl.AEX,
GPURefract.AEX and GPURipple.AEX this should keep it from freezing
on open.
However there are still other problems that arise such as Audio sync
problems
and more."
If you could disable "GPU acceleration", perhaps it would ignore those
plugins.
Or maybe removing them is enough.
One reason something like that might happen, is the video card usage model
in Vista and Windows 7 is different than previous OSes. There should be
some backwards compatibility, but perhaps Premiere is trying to talk to
the cards a bit more directly.
