Using mRemoteNG 1.75, Windows 7.
All Windows Updates installed, RDP 8.0 installed, all checked.
But, "RDP Check failed" and when I tried to connect to remote desktop I get "System.Runtime.InteropServices.COMException (0x80040154): Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))"
What I do wrong and how can I fix it?
