I cant get my new driver to install

I downloaded the 16mb detonatory 41.09 driver last night to my desktop and this morning when I go to install it, no go. It sits here on my desktop in a dos format that windows XP doesnt recognize, or wont let work. How do I get this to work?

Hmm maybe its corrupt...did you download the xp version and does the file have .exe extension?

Itt looks like you will probably have to download it again. Hope you don't have 56k
