I'm trying to download something off of the internet, but when ever i try to open the setup program I get the following message:

"Can't Run 16-but Windows Program"
"Cannot find file C:\DOCUME~1\NIELSV~1\LOCALS~1\Temp\SmallSetup\SETUP.EXE (or one of its components). Check to ensure the path and filename are correct and that all required libraries are available."

I assumed it was because I had it set so that I couldn't run 16 but programs. I'm on WinXP. I changed that (using regedit) and rebooted but it still didn't work. Ideas? Thank you!
