:rolleyes: Seems you talked with a sales droid instead of a software support person
CS3 might not work with 64bit flavours of Windows, and it might possibly also not work with Vista (for whatever reason - a sign for poor software design, IMO).
Good-old XP (32bit) should work, regardless of CPU installed.
So will get a new 32bit computer otherwise I'll need to spend thousands up-grading my software.
95% of all modern CPUs support 64bit technology. The rest is at the lowest end. You don't want to play CS3 with such a low end machine
