Can I use the same AFMG SysTune license under Boot Camp and in a virtual machine?

Yes, this is possible although AFMG does not recommend it. You need to understand the following background information and proceed with the instructions below to transfer your SysTune User Key between the different environments.

The licensing engine used by AFMG SysTune sees Boot Camp and a virtual machine as different computers.

To use one license under both environments the license has to be migrated from Boot Camp to the virtual machine or vice-versa.

To migrate a license from Boot Camp to a virtual machine open the AFMG License Manager in Boot Camp and upload the SysTune license.
Reboot the Mac and open the virtual machine.
Now download the SysTune license within the virtual machine.
