The automatic installation does not work at all. I got a somewhat running version by
- Installing .NET into a new Window 7 bottle
- Downloading and Extracting WinAuth-3.6.2.zip from https://github.com/winauth/winauth/releases
- Copying the exe file into the bottle
- Create a launcher and run manually.
Nevertheless in the running instance I'm not able to click any buttons via mouse. Unfortunatlely some OK buttons are inaccessible via TAB key.
