I'm having this error. I don't know what it means. The launcher.exe is in the game folder.

Download 2 file above and paste it to your folder game.
Already done that and still had that error.

I have found the fix. It seems that C9.exe is being treated as a virus of the Windows Defender that's why it's not locating the exe file. It needs to be whitelisted.
I cant get this thing to work.
installed client
got these 2 files from this page and replaced in game folder
installed vcredist
excluded from scanning by defender
still same error ...
Nop with my machine is all ok(EN US) but theres something to do with ICSharpCode.SharpZipLib.dll
all my other games and apps working fine without errors
need change encoding on pc, its in languages setup
To what and where? i did mess around many hours with google help but nothing changed.
Why it must be so difficult?
Can you make some pics to describe how and where?
