Vista unable to move/load big files.

Hey there. I recently downloaded a particularly large .exe (1.58 gigs) and when I go to run it, my windows explorer freezes up and I have to restart it. The same thing happens when I try to move it, so its stuck in my download folder. I then downloaded the lite installer for the game, that worked, but it has a bug, so I want to just run the big one.

Does anyone know why I can't run/move big files? I downloaded another unrelated exe last night, and I still cant run or move them.

Help appreciated
