I am planning to get a new PC, I have poser 11 installed on MacBook(where I I do most of the scene design), iMac and PC(for final rendering). PC is getting old, and I may be getting a new PC. How  and where do I remove the poser 11 licence off old PC and add to new PC when I uninstall poser on old PC and then install on new PC ?

Thank you, many kind regards
