Do you have .net framework 4.6.1?Debug version same this side. No error popup but in event viewer same error. I'm on windows 10. It seems to be on load error. Something is missing? My upgarde went from v 5.9.7.0 to v 5.9.7.2. I am a c# developer if that helps, if you need me to use a complier such as VS community version let me know.
