Why oh why won't AE CS5 run under XP Pro 64 bit?

Question

Francly, i'm getting fed up of this stupid CG world we live in where users have to juggle and zig zag in between the permanent idiotic capitalistic software development battles going on way above our heads for teh sake of profit.
I have a little pipeline  of 20 machines, couple of servers, couple of workstations and a bunch of render nodes. 80% which were set up with Vista (Pro Ultimatte and Business) had to be downgraded to XP Pro 64 for compatibity issues with some of the tools i was using, plug ins for 3ds max and AE mostly. believe it or not, downgrading from this piece of crap Vista did cost me money! ...and now that it is all finally running properly... the one tool i use for compositing in my pipeline that is AT LAST (and the last tool of its kind!!!!) 64 bit native.... WILL NOT RUN UNDER XP 64!!!! Which means that just because for reasons i absolutely ignore Adobe is forcing me to upgrade all operating systems on my network in order to finally benefit of what AE should have been able to do already for at least over a year! Wow! great marketting plan!
So i'm asking two questions here... and excuse my lack of formality....
1 -  ARE YOU FREAKIN KIDDING ME?????!!!!
2 - What are my options if i want to upgrade to AE and Premiere cs5 in order to finally make a full use of those within the 64 bit pipeline (that all my other tools are already set up for ...for years!!!!) without having to spend s#itloads extra in operating systems and other consequent upgrades? Cause as much as i'm willing to go with the flow... i'm just fed up with wasting my money over political decisions ADOBE, AUTODESK, MICROSOFT and more are making just to squeeze a little more each time.
pe@ce,

Answer 1

Obviously you did not really read my post, so i'm gonna make it more clear.
I was forced to downgrade to XP pro 64 bit in order to follow what you call "progress", in order to use new tools, new releases, new possibilities, such a Nvidia PhysX related tools which would not run under Vista 64 at that time.
Now instead of shooting in my legs and make me look like i belong to the prehistoric times, try to answer my question honestly and properly since you bother doing so. Not developping CS5 for XP 64 is either an agreement made with Microsoft, or a way to cut down costs on a development that was already a big fat money pit since it took ages to finally come up with a 64 bit version Premiere and AE, after YEARS of existence of 64 bit systems. You can try to make me look as dumb and bad as you want... but those are facts that don't make Adobe's purpose and motives look very neat.
Now to read from a "community professional" that what i thought was my legitimate request as a commercial user and active member of the industry is basically irrelevant because "it's all my own fault"... wow!
Now i don't have access to the same information you have it seems, but look at the amount of users who are still working in the caves like me running Win XP 64 for similar reasons and tell me if it is a considerate choice from Adobe to neglect them. As most professional in this business, i like to be informed and NOT FORCED! Seems fairly decent to expect from Adobe to be notified earlier... much earlier than on the release date of the upgrade that my set up will be obsolete!
And for the very same reasons i did not renew my Autodesk subscriptions... i shall not upgrade to CS5 and will look an other way to find a cheaper more "personal/people" oriented solution, one where the support will not slap in my face "it's you own fault" like ADSK and Adobe do when you tickle relevant topics.
Conclusion, i don't like it... and i don't feel i've put myself in this pinch, but thanks for your answer Mylenium, i'm one step closer to invest in The Foundry Nuke as a compositing solution and open source alternative for editing.
