Here you can retrieve your license key if you run into the following situations:

1. Have not received your license key after making the payment.

2. The key was lost when migrating to a new device.

Note: If you purchased PDF Reader from the Apple or Windows App Store, you don't need the license code. Simply click the "Restore Previous Purchase" button from within the app to retrieve your license.

It applies only to versions DMG v3.15.1 & WPF v2.1 or below. When the app is upgraded to DMG v3.15.2 & WPF v2.2 or higher, the old license key will be invalid. Please contact our customer service center at helpdesk@kdanmobile.com to replace it with a new license key.
