Blender 2.65a won't start

Hi,

I have downloaded both the Zip and Exe (from blender.org), both just won’t start. No Error, no Window appears (beside cmd)… If I run it from cmd just nothing happens as well. I reinstalled the vcredist, no change.

2.62 works flawless
OS: Xp 32bit

any Ideas?

Hm, work on my vista 32 labtop. Are you shure you load the 32 bit version?
Try to start blender in cmd with blender.exe -d
(You have to be in the blender folder)
This give more info on start.

Cheers, mib.
