ok problem solved - if anyone will have this kind of problem as we here - uncheck "run as admin" this specific exe file - "C:\ProgramData\FAForever\replaydata\bin\ForgedAlliance.exe" it looks like because of FAF replays have separate engine to run. this specific file which is used toi run replays ForgedAlliance.exe - is hidden in FAF folder in "replaydata\bin"
