Yep, just found it again, after #191

Absolutely no respect to my work <_< Thanks to me,

try to install msbuild tools (~20 MB): https://github.com/3F/DllExport/issues/29#issuecomment-284259126

Points exactly to "Microsoft Build Tools 2015" which solves the problem mentioned by @bbday later.

Anyway, again, regarding to #191

2021, I remind everyone, that was a temp solution. Modern 1.7.4 must work fine without everything that I suggested from original issue. For other case, please open a new one.
