I am not sure about 32 bit Vista, but 64 bit will not run Acrobat 7.0.
To load CS2 on to a Vista 64 bit system you have to change the install place. Go to this site.http://ntcompatible.com/compatoscat9.html
Click on; Adobe Creative Suite 2 Premium Edition, run down a couple of inserted messages and it will tell you how to enter the directory.
I've had no problems with installation nor function with Acrobat or PSCS2 on Vista 64.
Canon camera drivers however......
