How to Upgrade from the Trial Version of PDF Reader Pro for Mac?

If you purchase PDF Reader Pro.dmg through PayPal on official website, just download from official website.

If you purchase the paid version, PDF Reader Pro - Edit, Sign PDF, from Apple Mac App Store, you don’t need a license code, and directly download and install from the Mac App Store.

If you download the free version, PDF Reader Pro - Lite Edition, from Apple Mac App Store, and purchase All Access Pack, you don’t need to enter license code either, but to restore your previous purchase.

When you paid, but cannot run the full features, please check whether there exist different versions in your computer. If so, we recommend that you uninstall all PDF Reader Pro on your computer and then download and install it again from the corresponding channels.
