Anyone running 32bit of Vegas in Windows 7 64? How does it run? I want to do this because I still need Magic Bullet looks within Vegas.. but I would like to have more than 4GB of RAM available to my System. Will 32bit Vegas use up to 4GB of RAM provided my OS has that much available for Vegas?

I run both 32 and 64bit Vegas on Win 7 64bit. Works fine. I don't know that the 32 version can address more RAM on the 64bit OS. Seems like it shouldn't.

32 bit maxes out at 4GB.. so the 32 bit Vegas should be able to address up to 4GB Ram in a 64 bit OS right?

I don't know the technical answer, but Vegas will not run better if you have 8GB memory than if you have 4GB.

On the other hand, if you are running other programs at the same time as Vegas the extra memory may help.

If I bought 32 bit upgrade from Vegas 8 to 9.0 am I entitled to upload also 64 bit version from Vegas web site? Will it work with serial# I was provided for 32 bit update?

Yes, you get both for the same price.

Perrone, may I check if you are using a Dell XPS system? I had loads of issues with my Q6600 and Mac Pro. I have decided to upgrade next week but I wanted to be sure it works with WIN 7 64Bit V8 and V9.

I am using a Dell, but not an XPS.
