wine users - Aug 2010 - Installing a windows computer game on Mac using WINE

So I just finished downloading Wine. And when I try to install the computer game
through the command wine LeagueofLegends.exe'   , I always get the error:

err:seh:raise_exception Unhandled exception code c0000005 flags 10 addr 0x0


I have cd-ed to the correct directory (desktop) so I know thats not an issue.
Can somebody please help me solve this problem? I followed the following
