I just installed Vegas Pro 9 on Windows 7 64bit (iMac, Bootcamp).

When I launch the application I have an error message like this:

An error occurred starting Vegas Pro.
The TWAIN manager could not be initialized. TWAIN_32.dll missing or corrupt.

I already tried to replace the file in windows/system32 with a new downloaded from the internet but that didn't helped.

Any solution ?

Thanks
