If you are trying to install the UIC VPN but can't continue with the installation because everything is greyed out or only the AMP is available, this happens when there is a previous installation of VPN on your machine.
First, check if it is still installed:
- From the Finder go to the Application folder.
- Look for the "Cisco" folder and open the folder
- Then double click on "Uninstall Anyconnect" or "Uninstall Cisco Secure Client" start uninstall process
- Follow instructions to uninstall VPN program
- Reboot
If nothing is there here is the procedure for manually uninstalling the AnyConnect client:
Run the following shell script from the Terminal (top for AnyConnect, bottom for Cisco Secure Client):
$ sudo /opt/cisco/vpn/bin/vpn_uninstall.sh
$ sudo /opt/cisco/secureclient/binvpn_uninstall.sh
You will be prompted for your password. Once you enter it, just follow the steps and reboot.
If you are still having problems try this from the terminal.app and reboot:
sudo pkgutil --forget com.cisco.pkg.anyconnect.vpn
