I tried the new version on Windows 10 pro. Hardware as described. The same username and password that works with all other viewers without problem.
But with both the x86 and the x64 versions, when I click on the loginbutton nothing happens. Tried a restart of windows and then again. Nothing.
Windows 10 pro. Rizen 7 1700 CPU, 16 GB Ram, Nvidia 1060 6 GB GPU
Tried with firewall and antivirus on and off.
