For some reason, my computer will not let me open the McAfee security software I downloaded. (Double-clicking doesn't work, nor does the "open" menu option.) I was originally told to remove the Norton security software from my PC to get McAfee to work -- which I've done -- but the download still won't open. Once I received a message saying the download is "not a valid Win32 document." Can anyone please help me?
To be more specific, the "DMsetup" download was originally listed as "cancelled" in the download list. I clicked on the appropriate button to complete the download, but I am currently being prohibited from opening the file, either due to a virus or another program.
