help with Cisco VPN certificate

Archived from groups: microsoft.public.windowsxp.work_remotely (More info?)

I hope someone can help me....
I'm running XP and my machine crashed in the middle of installing VPN.
When I rebooted and ran the install prog again I got the message that
another version of VPN was already installed and would be removed
now...

Then the next screen said that I had to reboot...

Ran the installer again and got the same message - and so it went in a
circle

So:
-I deleted the VPN application
-I uninstalled the network adaptor
-I used regedit to delete asociated keys...
And I still get the same message.

So I figure that the installer is checking to see if there is a
certificate and using that to determine that VPN is already
installed...

Does that sound about right, and if so how do I delete the certificate
manually?

I need VPN for my work so I am in kind of a tight spot.

Thanks
