And additional info.. poser pro IS a 32 bit application. it just also has a 64 bit backgrund renderer.

What won't run? probably really old junk you most linkely don;t want to use anyway.

Hwever, there is supposed to be the ability to run xp as a launch platform for older programs from within vista.. there was a thread about it over in Daz's commons.

Never tried it, since there isn;t much at all I can't run.

You WILL find though that most applications are still 32 bit. Heck even the latest photoshop comes with 32 bit and 64 versions, both install, but you have to run the 32 bit version because all the plugins are written for the 32 bit version.

Some programs are way behind in ading improved 64 bit functionality.

Way too many people take way too many things way too seriously.
