Help, demos being Gay!

[915.0GT]

I downloaded a couple of game demos from download.com and only the Halo one worked. All the others come up without a program to run on, so when I double-click on one it asks me to choose a program. I need to know if there is a program I can download to run these or what to do? Thanks, Greg

By the way I'm basically computer retarded so be gentle if its a simple answer :D

What's the file name? Its probably a compressed file and you dont have a program set up to open it. Possibly .zip or .rar?

So you want what it says on the desktop? 'CodUO_SP_Demo' is what its called its type of file is 'file'. Its the game for Call of Duty - United Offensive SP Demo. I downloaded this one and a couple more and they all came out with no program to run in :(
