ScreenFlow User Guide | Preferences — Licenses
| Licenses are a part of the Preferences Window. The preferences window can be opened by selecting “Preferences” in the “ScreenFlow” menu, or pressing command-,. Then press the “Licenses” button in the tool bar. If you have not yet purchased ScreenFlow, you can press the button “Purchase License”, which will take you to our online shop, where you can purchase a license. If you already have purchased ScreenFlow, but a version with additional functionality is available, you will instead see a button “Upgrade License”. When you have received a license serial number, press “Enter Serial Number”; paste in your serial to unlock the application. If you have purchased an upgrade you will instead see a button “Change Serial Number”. If you wish to transfer your license to another computer, press “Deactivate Serial Number”; you can then enter your serial number on the other computer.
