It was working fine a week or so ago, and I just tried it today to get this issue. I was running 1.6.7, so I installed latest version

Windows 10.0.19043.

Hi justinl,

A FailFast crash occurs before Viscosity can actually launch. This usually means you have a corrupt .NET install, or have some intrusive developer tools trying to attach themselves to .NET or Viscosity. Please see the forum posts below for some ideas that may help: ... 8733#p8733 ... 273&p=6765.
