KI 3127 Cisco Secure Client “already installed” – Mac

(updated )
How to fix the error message: Cisco Secure Client can’t be installed on this disk. Cisco Secure Client is already installed.
If you previously deleted Cisco Secure Client from your Mac and are now trying to reinstall it, there is a high chance you will see an error message stating that Cisco Secure Client is already installed on the machine, which prevents you from continuing with the installation.



The reason is that Cisco Secure Client is not installed as a single app. During installation, the application itself is installed along with system extensions and other components, and not all of these are removed if you only delete the app. Cisco Secure Client includes a separate uninstaller app that can be used to remove the entire package, but if you have already deleted the app, there is a chance this will not work. Follow the steps below to resolve the issue.
Procedure
1. Run the uninstaller app (if you still have it)
  1. In Finder, search or navigate to Applications and find the Cisco folder.
  2. Inside the folder, check if you still have the app “Uninstall Cisco Secure Client.”
  3. Open it and click uninstall
  4. Next, open the Cisco Secure Client installation file again and see if you can install it now. If not, proceed to the next step.

2. Force your Mac to forget Cisco Secure Client
The reason you can’t reinstall Cisco Secure Client is that your Mac thinks it’s already installed.

Fortunately, it’s possible to force your Mac to forget Cisco Secure Client, which will then allow you to download and install it again.

Do the following:
  1. Open Spotlight (⌘ Command + Space)
  2. Search for Terminal and open the Terminal app.
  3. In terminal, write the following command:

    sudo pkgutil --forget com.cisco.pkg.anyconnect.vpn
  4. When you press Enter, you’ll need to enter your Mac password. Note that you won’t see anything as you type, so just type it in and press Enter.
  5. Once you’ve entered your Mac password and if the command was typed correctly, you should see the following response:

    Forgot package 'com.cisco.pkg.anyconnect.vpn' on ' / ' .


    The response confirms that Cisco Secure Client has been forgotten, and you should now be able to run the Cisco Secure Client installation file again and install it without problems.
