Blender won't install correctly on one of my computers I have two computers and have never had any problems with installing Blender, but now one of my hard disks crashed so I bought a new one.

I installed Windows 7, 64 Bit on it and some programs, but when I tried to install Blender, it installed it, but there seems to be something missing. The install wizzard said Blender requires 0 Kb of space and in the start menu there is no uninstall Blender. Furthermore, there is nothing in my AppData/Roaming....

When I try to open Blender, it just flashes the command console and then the grey screen flashes and then it's gone. This happened with 2.77a, so I tried 2.67b, which works fine on my other computer, but it had the same problem.

My other computer is older and I can't install 2.77 on it (no OpenGl 2.1).
I tried the MSI and the Zip file, but that makes no difference.

Any ideas?
Thanks.
Have you installed the necessary MSVC Redistributable packages after installing Windows?

I am not sure but you may need a few different ones from across the years to run Blender. Try at least the newest one
