I'm trying to install this Nortel VPN software onto a client's machine and that's the error I keep getting. I've tried shutting down IPSEC, to no effect. Anyone ever seen this before?

The system is a Compaq nx7400 running XP Pro. All Antivirus and firewall softwares have been shut down.

Apologies for posting this here as well as in the Networking forum, but I was getting no response there and am running up against a wall on this one.

Thanks much
