There are two ways you can choose to migrate the software:
Backup its contents using Export function (not always available) or File Open, then File > Save and reinstall the application on another PC or copy its installation directory to a USB flash drive.
Download a new version of the software to the PC, and use Dropbox or Google Drive to store the content of the software. Access Dropbox/Google Drive on the new PC and restore it within the application.
Note: For first version, you need to export the registry entries using Start > Run > regedit. Expand HKEYLocalMachine > Software > Developer Name/Software Name, then right click the folder and choose Export. Copy the exported file to the new PC as well and double click it to merge it into the registry.
