Hello guys :D i'm a new comer in ubuntu ;) i installed few days ago Wine for play Win game but i know that need Direct x to do it so i found this post : http://www.wine-reviews.net/wine-reviews/games/how-to-install-directx-in-linux-using-wine.html i did all that the writer wrote but when it says "launch direct x 9.0c install it gives me this error : The file '/home/davide/Scaricati/directx_9c_Dec04sdk.exe' is not marked as executable.
