Just adding in case someone finds it helpful. I tried it today on
Windows10. I had my MSVC installation in c:, so fsutil did not work until I
rebooted it in safe-mode. I first enabled the 8.3 format as

fsutil 8dot3name set c: 0

followed by setting shortnames for directory names that LO require because
on my Win10 installation there were no shortnames already set. In my case I
did (after cd-ing into respective dirs) :

fsutil file setshortname "Program Files (x86)" PROG~1
fsutil file setshortname "Microsoft Visual Studio 14.0" msvc~140
fsutil file setshortname "Window Kits" W~Kits

and then rebooted into normal mode. This solved the problem for me.
