Error on First Run in Windows: Solar Mutex not owned

[Oliver.Brinzing@xxxxxx (Oliver Brinzing)]

Hi,

with a recent build (win10 x64 Version: 6.2.0.0.alpha0+ (x64)
Build ID: d19482e191b8839f3b552e3b6e5e91ead70d565f)
i get several errors at first start (if the user profile is *empty*)

i noticed:
the folder " 'instdir/user/extensions" seems to cause the problem.
lo will start without errors if the folder exists.

Regards
Oliver
