You need to verify your upgrade eligibility if:
- PDFpen can’t find a previous version on your Mac
- You are purchasing an upgrade for someone else (and that is why PDFpen can’t find a previous version on your Mac)
To Upgrade
The easiest way to upgrade to PDFpen 9 or PDFpenPro 9 is to download them. When you launch, the app will locate any previous version, whether Mac App Store version or not, and offer upgrade pricing or a free upgrade;based on your purchase date.
To Verify
- Enter ANY past matching name and serial number combination. You can have all serial numbers associated with your email address sent to you if you don’t have them handy.
- Copy and paste names and serial numbers to avoid transcription errors.
If you have any questions, please contact us.
