Wait for the official reply but from what I seen so far, when you go to your "Account" you can see devices where app is "activated", when you uninstall you can "remove activation" by uninstalling but you can also manually de-activate a device on the account page. They allow up to 2 devices to be "activated" on single license (no clue if they can run app in the same time, have not tried). So you should be able to have it both on your desktop and laptop.
