I installed the blender after a fresh installation of windows 10. I have all the drivers installed. I have GTX 1060 graphics card. After running the blender, the console blinks and the program does not run. I text In the console blender.exe -d I have such error:

 found bundled python: C: \ Program Files \ Blender Foundation \ Blender \ 2.79 \ 
 pythonError: EXCEPTION_ACCESS_VIOLATION.

I'm trying install 2.79a version but 2.79 dosnt run too. Any ideas?

    $\begingroup$ Hi. I think it would be helpful to explain how the user should test those variables. $\endgroup$

  • $\begingroup$ I don't understand. There is nothing to test here. $\endgroup$

  • $\begingroup$ I think I meant to say 'set' instead of 'test'. My point is that you haven't told the user how to set the environment variable. $\endgroup$

  • $\begingroup$ How to set windows variables can be found googling for it. It's publicly available knowledge. $\endgroup$
