ok, adobe have just made an enemy for life!
The reason why it won't run on 2K or XP SP1 is... wait for it...
because of some security updates to the os? No
because of some necessary hardware or software support not available in other older OS's? No
because the installer programmer was too stupid to work out how to allow all os's? Sadly not.
No, it's something much more prosaic! The damn XP theme system - the whole reason I wouldn't go near that abominable pile of dog poo in the first place - the thing that brings you the teletubbie desktop! Bloody themes.
As a programmer I can think of many reasons to restrict the OS code runs on but the last thing you should ever do is restrict users based on the bloody user interface - that is the height of stupidity.
Obviously adobe feels form is more important than functionality...
Sorry, rant over
