Hahaha I see!
But I've run the mushclient.exe and it says like this.
C:\Users\Faelnar\Downloads\EternalWars\MSVCR110.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. And I've tried running it as an administrator. And my operating system is window 7. Do I have to switch to windows 10 so that I can play?
