I know I'm coming across this months later, but maybe I can shed some light for other users experiencing this same problem:
I used AppZapper to remove a copy of Cisco VPN I had installed on my system and ended up having the exact same issue as Glenn when trying to reinstall. What I did was this:

- Open Terminal and do the following:
- su (be careful when giving yourself root, of course)
- cd /opt/cisco/anyconnect/bin
- ls (to see if there's a vpn_uninstall.sh file)
- If there is, then run the following command:sh vpn_uninstall.sh
- You'll get this confirmation message in the Terminal:Successfully removed Cisco AnyConnect Secure Mobility Client from the system.
Now go back to your .dmg or vpn.pkg file (whatever your source for installing is). Now when you get to the Destination part, you should get no error and you can proceed with the installation.
Installing the VPN Client
- Download the AnyConnect VPN client for macOS 11.0 - 10.15 (Big Sur to Catalina) or macOS 10.14 - 10.13 (Mojave to High Sierra).
- In your Downloads folder, double-click the file you just downloaded to open it. An icon will appear on the desktop called AnyConnect, and a separate window will open.
- Double-click on AnyConnect.mpkg to run the installer, then follow the steps to complete the installation. NOTE: We recommend you un-check everything (Web Security, Umbrella, etc) except for the VPN and the Diagnostic and Reporting Tool (DART). This will give you a minimal install. The other features are not supported so there's no need to install them.
- Starting with macOS 10.13 High Sierra: During the installation, you will be prompted to enable the AnyConnect software extension in the System Preferences -> Security & Privacy pane. The requirement to manually enable the software extension is an operating system requirement.
