CS3 won't launch - help!

I just purchased a new HP system. Trying to get it set up tonight.
it is:

Vista 64bit
8 gigs of ram
AMD Phenom 6750 quad core
nVidia 8800 GTS with 640 megs of DDR
I have installed all the updates, installed the latest nVidia drivers
I uninstalled all the crap, such as norton, and all the HP BS-ware.

PS installed without error, but when I try to launch it, It opens the main window, but it is all greyed out.... the curser does the wait swirly deal... and then after about 3 miutes, it repores (not responding) in the title bar.

I REinstalled CS3 AND ran adobe updater, and it added several updates to it, but still when I try to launch the program, no dice.... it hangs after opening the main window.

I installed LR 2.3, not problems.
Bridge launces without a problem.

What gives?

Thanks,

See if right clicking and launch as admin helps

yeah, tried that. No change.

anyone? No patches, fixes or magic to make it work on 64bit?

This thread talks about a brand new patch for CS4 64 bit.

This may be a last resort if you cant fix it, but I had some crashes a while back, and only completely un-installing the program worked. I had to use a program called Your Uninstaller 2008 to completely erase the registry. Try that if it doesnt work.

Will this help?
