I think I have fixed my problems. I have only done two simulations tests but both worked fine.

The problem appears to be the version of Python I had.

The Windows10InsiderPreview computer had Python 2.7.12(64bit). I uninstalled that and installed Python 3.6.0a4(64bit) and have been able to run Hair simulations of 311 frames with Victoria4.2 (as Collision) and Maria hair (as Hair) and also Victoria4.2 and Nwear_shirt (as Collision) and Maria hair (as Hair) without error.

My Windows10 computer has Python 3.5.2(64bit) installed. When I get time I will uninstall that and install Python 3.6.0a4(64bit) on it and see if that fixes the problems I was having with it.
