[Walter Soyka]What if a facility wanted to add an Adobe license, but they were still running CS4? Can they call Adobe and order one, or will Adobe only sell them a new license for CS5.5 and a pile of upgrades for the other workstations?
I don’t know if you can call Adobe up and order a license for an older copy, but I just checked on Google and CS4 versions are available from a wide variety of legitimate sources (including Wal-Mart).
Additionally, CS4 versions of Premiere and After Effects were bundled with Master Collection CS5 (not sure about the other collections) in case you needed backward compatibility with plugins or wanted some of the new CS5 versions while still working in a 32-bit environment.
Plus, you can always open older projects in CS5/5.5.
