Install Acrobat DC via the Creative Cloud Desktop Application

The most common reason for this error is installing Acrobat via a standalone installer rather than through the Creative Cloud manager.

Acrobat DC included with a Creative Cloud subscription uses a different licensing mechanism than the standalone perpetual version. If you downloaded Acrobat directly from an external link or an old installation disk, it will ask for a serial number.

1
Uninstall the current version

Remove the incorrectly installed Acrobat DC from your system using your computer's standard application uninstallation settings.

2
Open Creative Cloud

Launch the Creative Cloud desktop application on your device.

3
Sign in with your Adobe ID

Sign in using the email address and password associated with your active Creative Cloud All Apps subscription.

4
Install Acrobat DC

Navigate to the 'Apps' tab within the Creative Cloud desktop application, locate Acrobat DC, and click 'Install'.

Install Acrobat DC via the Creative Cloud Desktop Application
Licensing Automatically Applied: Installing through the Creative Cloud desktop app automatically ties the Acrobat DC software to your active subscription, bypassing the need for a serial number.

Frequently Asked Questions

Why does my Adobe software keep asking for a serial number?

This usually happens if the software was installed from a standalone installer rather than the Creative Cloud app, or if your login session has expired. Always install apps directly through the Creative Cloud desktop client to sync your subscription license.

Can I use Acrobat DC without a subscription?

Acrobat DC requires an active subscription or a purchased perpetual license (such as Acrobat Pro 2020) which provides a serial number. If you have a subscription, you must sign in with your Adobe ID instead of entering a serial number.

How do I check if my Creative Cloud subscription includes Acrobat DC?

Log into your Adobe account online, navigate to 'Plans and payment', and check your active plans. The 'All Apps' plan or a specific 'Acrobat Pro' subscription will list Acrobat DC as an included application.
