after downloading the new patch , I try to run it but it says I need the disk to do that , I downloaded the game from GOG so I have no disk , it also says to select a file to place the patch , where does the file go ?>

disk=dd

You need 7GB on your c drive and the 7 gb or you installed your game

current patch consists of two files
a small exe and a huge bin file
you need both, the exe alone is not sufficient
