I am using windows 7 64-bit, freshly installed. I installed Blender 2.73a but after installation, when I open blender it crashes (Blender has stopped working), but Blender 2.68 works perfectly fine.

A similar question has been asked before but the solutions haven't helped.

  • $\begingroup$ i fix it myself. i followed a solution similar to my problem, by copying the python34 folder to (2.73/python) it worked, but, everytime i press shift z (rendered view)it crashes. I guess i'll just have to use 2.70 until someone has fix this issues in later versions, by the way thanks everyone. $\endgroup$

If the problem is related to having a PYTHONPATH environment variable set, you can do the following so you don't have to modify your PYTHONPATH variable. I am running 2.75a and this fixed my problem.

  1. Make a batch file somewhere like your desktop
    • To do so, create a blank .txt document and name it blender.bat (MAKE SURE THE EXTENSION IS .bat and not .txt)
  2. Edit blender.bat and add the text below

    set PYTHONPATH=""
    cd C:\Program Files\Blender Foundation\Blender\
    start blender.exe
  3. Your blender path may be different, so make sure you find the correct path

  4. run blender.bat

This will temporarily set the PYTHONPATH to "" (nothing) during your blender session but is restored after you close.
