Q. What does it mean when I get "Error msg: failed to find the uninstall file..." while trying to uninstall VPN Client? Also, what needs to be done to successfully complete uninstallation?

A. Check the networking Control Panel to ensure that the Deterministic NDIS Extender (DNE) was not installed. Also check for the uninstall file by going to Microsoft > Current Version > Uninstall. Then remove the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\{5624C000-B109-11D4-9DB4-00E0290FCAC5} file and retry the uninstallation.
