Product
PDF Editing Software
Device & OS
not provided
Scenario
Installing and activating a premium PDF editor on a second computer or laptop.
Observed behavior
The software requests another purchase on the second device, typically due to an incorrect account login or reaching the maximum device activation limit.
Before you start

Ensure you have the exact login credentials for the account originally used to purchase the PDF editor, and verify your subscription plan's maximum device limit.

Solution 1Recommended

Sign in with the Original Purchase Account

Log into the PDF software on the new device using the exact account tied to your purchase to restore premium access.

2
Locate the sign-in option

Launch the application and click the 'Sign In' or 'Account' icon, usually located in the top-right corner of the home screen.

3
Enter your credentials

Input the email address and password that you originally used to purchase the premium license.

4
Verify activation

Navigate to the account settings to confirm your premium status is active. If prompted, click a button labeled 'Restore Purchases' or 'Activate'.

Sign in with the Original Purchase Account
Account verified: Once signed in, all premium PDF editing tools should be immediately available on your second device.

Frequently Asked Questions

Why is my PDF editor asking me to pay again on my new laptop?

This usually happens if you are not signed into the specific account used to make the initial purchase, or if your subscription limits the number of active devices. Verify your login credentials and check your license terms online.

How do I find out how many devices my PDF license supports?

You can check your device activation limit by logging into your account dashboard on the software provider's official website and navigating to the 'Subscription', 'Plan', or 'License Details' page.

Can I use the same PDF editor license on both Windows and Mac?

It depends on the specific software provider. Some licenses are cross-platform and work on both Windows and Mac with a single account (like WPS Office), while others require separate purchases for different operating systems.

What should I do if I uninstalled the software but it still says my device limit is reached?

Uninstalling the software from your computer does not automatically deactivate the device on the server. You typically need to log into your web account dashboard online and manually remove the old computer from your list of activated devices.
