hi................................

please help

There is a document at Dassault's website, 3ds.com regarding Vista compatibility. There are two Windows KB updates that need installed. Sorry, I don't know the numbers.

Also, Dassault told me that they have only tested Vista Pro. I tried running with Vista Ultimate 64 bit and we can't get it to work, and we have to downgrade to XP Pro 64 bit. This is Catia Version 5 r 18.
