Multiple Registrations Win/Mac

[Gabesaurus]

I downloaded PT4 to my other computer which uses Windows. Can I register it there as well (HM allows 2 installations) and if so how can I find the registration code to do so?
thanks,

Yes, you can use your license on any two computers concurrently (that you own and operate), and a mix of Windows and Mac is fine. You can access your code via My Account > Registration Codes at the top of this page.
