Uninstalled previous version of Cisco VPN and installed latest version of Cisco AnyConnect Secure Mobility VPN client. ERROR: 'The VPN service is not available.

1. Service Unavailable Cisco Anyconnect Download
2. What Is Cisco Anyconnect

The VPN service is not available. My solution is to uninstall the Cisco ANyconnect, and delete folder Cisco ANyconnect under Program Data, and restart. Install again with the same version. Without removing previous folder it will not solve the issue. Note This issue is unrelated to the VPN features of the Cisco AnyConnect software. This issue is specific to the wireless NAM component of the Cisco AnyConnect Secure Mobility Client. This issue is resolved in Cisco AnyConnect Secure Mobility Client version 3.1.05182. Please see Cisco's release notes for more information. Aug 24, 2020 Symptom: AnyConnect NAM service no longer works after upgrading Windows 10 to build 1703. AnyConnect UI shows 'Service Unavailable'. Conditions: This issue will occur when upgrading to Windows 10 Anniversary Update, version 1703.

Installing the VPN Client

1. Download the AnyConnect VPN client for Windows. Note: If you're using Microsoft Edge, the program will download as a 'sys_attachment.do' file. You will need to rename the file to 'sys_attachment.msi'
   • If you have the Windows Surface Pro X tablet with an ARM-based processor, you should download the AnyConnect VPN client for ARM64.
2. Click Run on the Open File – Security Warning dialog box.
3. Click Next in the Cisco AnyConnect Secure Mobility Client Setup dialog box, 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 the VPN Client

1. Go to Start->Programs->Cisco->Cisco AnyConnect Secure Mobility Client to launch the program.
2. Enter vpn.uci.edu in the Ready toConnect to field, then press the Connect button.
3. Select your desired connection profile from the Group drop-down menu:
   • UCIFULL – Route all traffic through the UCI VPN.
     • IMPORTANT: Use UCIFULL when accessing Library resources.
   • UCI – Route only campus traffic through the UCI VPN. All other traffic goes through your normal Internet provider.
4. Enter your UCInetID and password, then click OK.
5. A banner window will appear. Click Accept to close that window. You are now connected!
