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.

try deleting everything in %appdata%\Blender Foundation\Blender before installing

open explorer, copy/paste this : "%appdata%\Blender Foundation\Blender" in the adress bar
Delete everything you'll find in this folder
