i am trying to uninstall a program (netbet pro) through Add or Remove Programs. As soon as I hit Uninstall, I get a popup "Windows Installer" with the message "The feature you are trying to use is on a CD-ROM or other removable disk that is not available. Insert the Netbet Pro disk and click OK." This program was installed from a webpage, not a disk. I have also had the same problem when trying to Install AVG Antivirus, I get the same popup "Windows Installer" with the same message. What could possibly be causing this??
