-> Hi Marc, I think Anthony's blender.exe build is a 32-bit build, and you can't "mix-and-match" 32-bit and 64-bit .exe and .dll parts together.

Hi Michael, It's with the 32bit version of blender that I tried.
The original 2.49b 32bit version works on the 64bit os.

Maybe it will work with the 2.5 version, I will try later.

Marc
