Vpn Error 51 Mac 10.6

tried reinstalling and everything.. I would be very glad, if someone has suggestions what to do. Florens from Germany TŁbingen #146 | Tuesday, April 21, 2009 8:09 PM So i fixed the problem: (Running Mac OS X 10.4.11) First i uninstalled current version with: terminal: sudo /usr/local/bin/vpn_uninstall Worked great!

Disable all Parallels network adapters in the network preferences. Sorry, I don't have a suggestion for you outside of reinstalling the Cisco VPN software. Where can I download the Cisco AnyConnect VPN Client?A.Open theCisco Support Page.Click Download Software.Choose Products > Security > Virtual Private Networks (VPN) > Cisco VPN Clients.For version 3.0, chooseCisco AnyConnect Secure Launch VPN client again.
