Its good that S3D now supports VM. I was wondering what happens if there were a problem with the VM and I needed to start over, how would I de-active the product in order to re-install in another VM.
Just login to your S3D account on their website, go to Devices, and find the one you need to reset. It says pretty clearly that you should only use that for extreme circumstances though, but I think a crashed hard drive would qualify for that.
If you just need to relocate a license normally and you still have access to the computer, just uninstall the software and choose Yes when it asks if you want to remove your license.
