on startup my blender version 2.77 crashes, have any off you been through this and know a solution? I have already tried re-installing it but its no use. Thanks
Do you have another version of Python installed on your system?
My version of Blender 2.75 would not start in Win10, complaining about unhandled exception 0xc0000409.
I re-uninstalled Blender 2.75, re-installed the MS Visual Studio redistributable (msvcr120.dll), went through the usual windows service troubleshooting steps starting from a clean boot. All no help. I finally ran the Program Compatibility troubleshooter on blender.exe, the diagnostics log in %appdata%/temp said "python incompatible".
So I deleted the PYTHONPATH environment variable. Voila! Now Blender starts fine.
