I find this rather odd. Premiere won't even install on a non-SSE system, regardless of OS. Aabout two years ago, after obtaining Premiere Elements(bundled with PSE), I ended up building a new PC just to run it. I wonder why Adobe allows it to install on a non-SSE system, considering their stance on pre-XP operating systems?
