I lost my serial number, what can I do to get it back?
If you still have the original invoice email that was sent to you at the time of purchase, you should find your licence number there. If you deleted this email or do not have access to it, please visit the Serial Number Retrieval page for further information. This will take you to eSellerate's after-purchase support page, which will allow you to look up your serial number. (eSellerate is the e-commerce provider that runs our web store.) If you still cannot find your serial number, please drop us a line.
Please note, however, that we will be unable to retrieve serial numbers for purchases made more than ten years ago: to comply with data protection regulations, eSellerate automatically deletes customer information older than ten years.
If you purchased from the Mac App Store, you will not have a serial number. You will need to use the Mac App Store software to re-install the program.
