On someone's suggestion, I downloaded a program I thought I could use and it didn't work. When I tried to uninstall it, the uninstallation process was incomplete. There are still three files which refuse to go away.

I tried to simply delete them, but I get the message:

"Click Apply. If you are prompted for an administrator password or confirmation, type the password or provide confirmation."

How does one provide confirmation? I can't find that in Windows Help.

Thank you.
