Unable to upgrade or uninstal Cisco VPN Client

I am trying to uninstal the Cisco VPN client from a laptop. It was installed by the user and has never worked. The install via the CP has not worked so I have followed article 18840 from Cisco which has not worked either.

When I install after completing the above steps I get an error saying I need to uninstall the previous version. Does anyone know of a cleanup tool for this?

The problem is the Cisco service (from previous install) starts after you do a fresh install and settings not match.
You need to:
1.  Uninstall
2.  Delete all reg keys - including the the service key (not mentioned on Cisco kb)
3.  Reboot
4.  Copy the VPN client install files into its own folder
5.  Install client

I have this fixed now. None of the above worked although they were great suggestions I had done most already following my own research etc, this seems to be a common issue. I had an old VPN client also , I ran the installer for the old version and it actually removed the remaining files that the was preventing install including some Netscreen files (which wrer only on teh Laptop for testing). After I did this it worked.
