Blender 2.70 won't run

Hi :DI have just download and installed Blender 2.70 but when I run in, both normally or as admin, the cmd prompt appears then disappears as normal but then Blender doesn’t load. I am running Windows 8 64 Bit and I have updated my graphics chip to see if that made a difference but it still doesn’t work.Last year I had the older version of Blender installed, I think it was running fine on this computer but I am not sure as my PC broke last year that had Windows 7 and I am unsure of the time frames lol Does anyone have any possible solutions? Thanks.

Just tried installing the 32 bit version and it works fine, strange :open_mouth:
