I think it's a software problem, but not sure if caused by our software or some Windows component.
Crash occurs in a function used to launch CPU threads. It's widely used and very dependent of the OS. Unfortunately, the error log doesn't show more information (not rare when analyzing minidumps). We have not similar cases reported either.
Please, send us the minidump of 2014 to be sure it's the same problem.
Thanks,
