CS1, CS2, CS3 and CS4 are dead & gone. The aging activation servers failed and were taken offline. Even if you find an installer, it's impossible to activate the software.
CS5 and CS6 are on life support. But they can still be activated providing you have the following: 1. your original media (disks or downloads) you received at purchase and a way to read them, 2. a legitimate serial number for that version, language and platform (Win/Mac) and if it was an upgrade, a qualifying serial number from a
in general, you should avoid using time machine with any adobe programs: it's more likely to cause problems and work for you than it is to save you some effort.
again, in general:
to use cs6, you need an os that supports 32 bit programs, and as @Nancy OShea pointed out, monterey does not.
you either need an older os to use with cs6 or, again as @Nancy OShea pointed out, you need a newer software to work with your newer os.
however, some adobe cs6 programs were 64 bit while their installers were 32 bit (eg, ps). so while you can't install ps on monterey, you might be able to migrate it to monterey. if that fails, there's nothing i know about that you can do to get it to work, but if it succeeds it salvages a almost hopeless situation.
