portable

Good morning,
I have so far used the free version of 4k video downloader.
I would be interested in purchasing the license for not having the limit in the playlists, possibly the bundle.
I usually use virtual machines but I wonder if the license is tied to the virtual or physical machine.
Because if it's tied to the physical PC, it's not a problem, even if I re-create the virtual machine, otherwise I should use the portable version and use it on the physical PC, hoping it will not go in any way to load libraries or modify the windows registry.
Thank you.
Best regards
Luigi Fiorini
