[Wine] winetricks won't open from terminal

------------------------------------------------------
wine cmd.exe /c echo '%ProgramFiles%' returned unexpanded string '%ProgramFiles%' ... can be caused a corrupt wineprefix, an old wine, or by not owning /home/mike/.wine

I'm new to linux so does anybody have a fix for this? I'm trying to play LoL on here but I need extra packages from winetricks, and  it won't open. Please help!
