There are 3 main causes so far for problems like this.

Windows not updated.
You really really really need windows to run all windows updates on windows vista or 7. For windows 7 you need SP1 installed and for Vista you need to be fully updated.
Please check this, it is the most common cause of this problem.

Python related
Having PYTHONPATH, PYTHONHOME or any python related environment variables causes blender to try and use an incompatible version of python.
Even the official windows 3.4 python is currently incompatible as that is compiled with Visual Studio 2010 and does not include a proper manifest. Loading that will crash 100% either silently of with a message like the one posted above.
Please make sure there are not PYTHON related environment variables set.

OpenGL related
Please test with a software opengl driver
Download this dll and copying it so its located in the same directory as 'blender.exe' and run Blender normally.

Marking as incomplete until these things are tested...

Python related. Having PYTHONPATH, PYTHONHOME or any python related environment variables causes blender to try and use an incompatible version of python.

Philipp, thanks! you are right, the second option is causing the issue. We are recently trying some development with Oculus Rift and some Python libraries have been installed on that pc.

Perhaps someone could develop a .bat file capable of storing environment variables, shut down them, execute blender, and recharge them at the end of the Blender session?

PD: task solved, please close it
