Parameter is incorrect

My friend is having trouble installing and getting this game to work on his computer.

He is running Windows 7 Ultimate 32-bit. He installed the vcredist_x86 only, and not the vcredist_x64. He tried uninstalling and reinstalling. He tried deleting config.xml, and that also did not work. The error that comes up is always the same error, and it occurs when he attempt to start the program. The Client doesn't even appear.

Attached is a picture of the error. Thank you for any and all help.
