I am having a problem uninstalling Cisco VPN Client 4.6.00.0049. The application hung on uninstall from add/remove programs and system now keeps trying to uninstall after reboot. The application cannot uninstall and if I try to reinstall it says a previous version has been installed and a reboot is required. It's just a cycle of reboots since the system is continually trying to uninstall. I have tried some of the other suggestions from EE posts and also Cisco website, but no luck. Some errors received include "Remove Plugin Failed" followed by Error 1722 and then a request to reboot to complete the uninstall. Also receives error 28005 if you try to install or open VPN client after uninstall fails. Windows Installer clean up does not show Cisco VPN Client in the list. Any help would be appreciated, so I can cleanly remove this version and install 5.4. Thanks.
