Product
Adobe Acrobat Pro DC
Device & OS
not provided
Scenario
Activating a perpetual license for Adobe Acrobat Pro DC after installation.
Observed behavior
The application displays a purchase prompt, often because the installed edition is a subscription version that does not match the perpetual license or the user is signed into the wrong Adobe account.

Solution 1Recommended

Reinstall the Correct Non-Subscription Acrobat Installer

Uninstall the mismatched subscription version of Acrobat and reinstall the standalone version that accepts perpetual serial numbers.

Acrobat offers different installers for subscription (Continuous track) and perpetual (Classic track) licenses. If you install the subscription version, it will ignore your serial number and ask for payment. Reinstalling the correct Classic track installer resolves this.

1
Sign out and deactivate

Launch Adobe Acrobat, click on 'Help' in the top menu, choose 'Sign Out' to log out of your Adobe account, and deactivate the current installation.

2
Uninstall the current application

Navigate to 'Programs and Features' in the Windows Control Panel, locate Adobe Acrobat DC in the list of installed programs, and click 'Uninstall'.

3
Restart your computer

Reboot your system to ensure all background Adobe processes and temporary activation files are completely removed.

4
Download the matching installer

Go to the official Adobe download page and specifically download the non-subscription (Classic track) Acrobat Pro or Standard DC installer that matches your perpetual license.

5
Install and activate

Run the installer. When prompted during the setup wizard, enter your perpetual serial number and sign in with the correct Adobe ID linked to the purchase.

Reinstall the Correct Non-Subscription Acrobat Installer
Creative Cloud Conflicts: Having other Creative Cloud applications installed (like Photoshop CC) can sometimes interfere with perpetual Acrobat licenses. Ensure you are using the standalone Acrobat installer.

Frequently Asked Questions

Why does Acrobat ask me to buy when I already entered a serial number?

This typically occurs if you downloaded the subscription-based (Continuous) installer instead of the non-subscription (perpetual) installer. The subscription version will not recognize perpetual serial numbers.

How do I check which version of Adobe Acrobat is installed?

Open Acrobat, click on 'Help' in the top menu bar, and select 'About Adobe Acrobat'. This dialog box will display your exact version number and indicate whether it is on the 'Continuous' or 'Classic' track.

Does having Photoshop CC affect my Acrobat license?

Yes, having Creative Cloud applications installed can sometimes cause the Adobe Desktop App to automatically update Acrobat to the subscription version, causing a mismatch with your perpetual license.
