Cisco AnyConnect is a complex VPN tool that helps remote workers access enterprise resources in a secure, effortless manner, from any supported device.

This software utility also integrates advanced protection in order to block malware at endpoints, thus ensuring a safe work environment.

To be more specific, during installation or while trying to launch Cisco AnyConnect, users would be prompted with an error message:

As it turns out, this issue is not uncommon and has a couple of easy-to-follow fixes. Check them out below:
