search for: unexacutable

Lord of the Rings Online is free, so I tried to download and play it. However when I tried to install the game from the terminal (because when I downloads something, It always says: unexacutable bit) It did the usual SHELL_execute thing then after that this came up: err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr (nil) Can anyone tell me how to or if I can fix this.
