When I try to activate FoolCat (licensed or a trial), why am I told, “No virtual machine activations allowed.”?
This only concerns Windows users.
Running FoolCat in a VM is a Pro feature.
If you see this error when activating a trial, you're running FoolCat in a VM, or a Hypervisor process must be active in Windows.
If you see this error when activating a purchased license, you have a regular license or a Pro license that needs VM activations allowed on your license.
