ForceBindIP for LoL Client

hey guys im trying to use my wifi connection only for lol, and my lan adapte for everything else, i tried to get it work the whole day but i didnt succeeded, the link i attached is a program that should make it possible, but it's very old and outdated, can someone rewrite, compile and upload it ? you need visual studios to compile it (it's a very small text, dont worry but i dont understand anything of it)

thanks so far
