Windows 10 64 bit, R2.6.12_r160723 fails

[Khun_Doug]

I have uninstalled the older version and then later this version, and then did a clean reinstall and restarted the PC. This version will not start on my system. Previous versions have been working. I'm falling back to r160722.

Should be fixed, win64 done, win32 builds in progress
