Cisco VPN Client error: "Reason 442: Failed to enable Virtual Adapter"

So, this Cisco VPN error blighted my productivity for a few days:

"Reason 442: Failed to enable Virtual Adapter"
Apparently, this is caused by the Cisco VPN installer placing the wrong adapter name in the registry during installation. Seriously??? A registry hack is what it takes to fix this??? Booooooo, Cisco.

Follow these instructions.
