You may get a warning from Vista about compatibility with CS2. I think 
this is leftover from pre-release days where there were issues with 
Vista's desktop windows manager (the thing that gives you transparent 
frames, etc.) You can tell Vista to not warn you about this again.

I have not seen any actual problems running 9.0.2 (the last update) 
under Vista 32 or 64 bit. I ran that way for more than a year before 
upgrading to CS3.
