I have CS5 applications, and older Premiere/related (Audition2) software. I'm thinking for the CS5 applications, since they use 64-bit, I may need to re-install them after upgrading OS and RAM. Is this what I should do and is there a process I should follow?
XP64 is long dead. What you are trying to do is utterly pointless, especailly since neither After Effects, Premiere Pro nor the 64bit version of Adobe Media encoder will run. Likewise, Photoshop 64bit will not/ may not be able to use hardware acceleration. Upgrade to Win 64 and get CS6/ Creative Cloud or just leave things as they are now. Everything else is a waste of time and money.
