Hello Maximus,
I have new build of Windows 10 21H1, have a error to execute l2.exe "Your Windos OS version is not supported."
I try open in CMD prompt ADM but not execute, try compatibility mode ( XP, 7, 8 ) not working.
Its a problems but is next version of Windows 10.
This moment i use another PC to connect in the server, but is a future problem.
Thanks for your attention.
Congratulations for work in this server.
Bye Bye!
