It says it's the vista version, but that's just MS-speak for "we still think our users can't tell the OS from the app"...it works on 7 just fine.
The "Live Essentials" video editor may be OK for what it sets out to be, I guess, but it's not Movie Maker as it has been for 10 years or so. It's almost like a Microsoft product came out that wasn't backward-compatible...oh wait. It would be pretty neat-o if anywhere on the live pages they mentioned "Oh, that thing that we distributed for ten years that you may want? Here's the link!"
"Sucking my balls" was the least of what i wished upon Microsoft's "program managers" when I found out that I couldn't work on my years of accumulated movie maker projects.
Good luck!
