Sketchup crash at start

Hello everyone,
I’m helping a friend installing sketchup (make) on his desktop with Window 7 64bit (With an old GeForce 315). He had version 8 installed then I upgraded to the lastest version and, since then, it stopped working.
It simply crashes at startup. I’ve also tried reinstalling, updating drivers to latest version and others suggestion in the forum… nothing helped.

Looking at the dump file it is something related to x64-msvcrt-ruby200 NULL pointer exeption.
Here’s the dump file:
SketchUp.zip (21.5 KB)

Any suggestion?
Thank you

Try the 32-bit edition.
