If you have purchased a ProPresenter 6 Single User License for Mac or Windows, but need to change platforms, there is a $99 fee. This can be purchased through our Store by going to the ProPresenter 6 License Upgrade and Conversion page. To purchase this at $99, this would be the Crossgrade option. Please note that the Crossgrade will disable your current license and give you a new Single License code on the opposite platform. This action is not reversible and the only way to go back to the previous platform would be to pay the Crossgrade fee again.
If you think that you may need to switch again or you plan on needing to use both platforms in the future, you may want to consider upgrading to the Campus License which will cover both the Mac and Windows version. The Single to Campus conversion option is also available on the Upgrade page and is $500. Not only are you able to use the Campus License on Mac and Windows, you can also use the software on as many machines as you need on your Campus.
