.zip problems
 

Hey,
I've downloaded several games in this form:
.zip file with a setup thingie on it. I cant run the file without unzipping it. So i try to unzip it. its a no-go. I get this message:
"! Cannot execute "C:\DOCUME~1\JIMMYH~1\LOCALS~1\Temp\Rar$EX00.843\S etup.exe"

By the way: im using WinRar. I tried the standard windows extracter and it said that the file was blocked and i could unblock it by pressing a button in a menu. Went to the menu, no button. So im using WinRar

Any help would be great,
Thanks in advance.
