Gotta love windows 10, lol. I know when I tried to install 2.76b and 2.77 on my new computer, I couldn’t get blender to run when using the zip method of downloading and had to use the msi method. All my other computers I could use the zip method.
Since I got Win 10 never really had install problems at all
only with this 2.78
and again here it seems it was probably because of an error in 2.77 which is very strange
for some file ID which were wrong
anyway will see when they come out with new version
