#4 Bug in PUK program?

[Anonymous]

I've downloaded PopUp Killer three times from
SourceForge.net. Every time I try to install it, I get an
error box that says: "Failed to load control 'INET' from
MSINET.OCX. Your version may be outdated. Try
using the version that was included with the program."
I'm using Windows 98 on a public library computer.
Also: Does PUK have the ability to close stubborn
browser windows?
