The software itself you will need a new version if you are changing from Mac to Windows PC.
I am not sure if the license is locked to a particular machine or platform.
As far as I know it is just a number that you must input when you start the software.
If that is the case then it should work on both.
I could be wrong though.
Best option is just to try it yourself.
If you need to download a new license you will soon find out.
As I say though, you will definitely need the Windows version of the software.
