Cisco VPN Uninstall

Hi

I installed cisco vpn on my Vista Home laptop.
It didn't install correctly so I went to remove it. It didn't show up in the default programs to uninstall it so I did a google search and found instructions on how to do this manually by removing keys via regedit and then deleting the program folders. This didn't work as there were errors while deleting DNE.

Has anyone got a method to remove cisco vpn? So that I can try an install it again?

I would reinstall it and then remove it correctly. Otherwise, reinstall your OS. It is very complex in its install.
