I use FastTrack Schedule on a Mac. Why doesn't my serial number work when I install it on my Windows machine? I use FastTrack Schedule on Windows. Why doesn't my serial number work when I install it on my Mac?

When purchasing a license for FastTrack Schedule, the customer is purchasing a Serial Number for a specific platform - either Mac or Windows. A Windows computer will not accept a license of FastTrack Schedule for Mac and vice versa. Although FastTrack Schedule can be installed on both platforms, the customer must purchase a separate license per platform.
