- not provided
- Scenario
- Downloading an e-book requiring Adobe software activation.
- Observed behavior
- An error message appears stating that the application has been activated on more than the allowed number of devices, preventing the user from authorizing the current device.
Ensure you have your Adobe ID and password ready, and verify which of your currently activated devices are no longer in use.
End Active Sessions from Your Adobe Account Settings
Use this method to manually deactivate old or unused devices, freeing up activation slots for your new device.
Adobe imposes a strict limit on the number of devices you can authorize simultaneously. By ending active sessions on devices you no longer use, you can instantly resolve the activation limit error and authorize your current application.
Open your web browser and navigate to https://account.adobe.com/security.
Log in using the Adobe ID and password associated with your e-book or application.
Go to the 'Account and Security' tab and select the 'Sign-in and security' option from the menu.
Scroll down the page until you find the 'Active Sessions' section to view all currently activated devices.
Identify the devices you no longer use and click the option to end the sessions for those specific devices, then try activating your current device again.

If managing active sessions doesn't resolve the e-book download issue, specific DRM errors can be addressed by the Adobe community.

Frequently Asked Questions
What is the maximum number of devices I can activate on an Adobe account?
For most standard Adobe subscriptions and Adobe Digital Editions, you are typically allowed to activate the software on up to two computers or devices simultaneously. Attempting to activate a third device will trigger the activation limit error.
Can I remotely deactivate an Adobe device I no longer have access to?
Yes, you can remotely deactivate a device by logging into your Adobe account online, navigating to 'Sign-in and security', finding the 'Active Sessions' section, and ending the session for the unavailable device.
Why do I get an activation limit error even though I only have one computer?
This can happen if you recently formatted your hard drive, reinstalled your operating system, or upgraded major hardware components without signing out of Adobe first. The system registers the new installation as a brand-new device, eating up your available activations.
Does WPS Office have device activation limits like Adobe?
WPS Office allows you to sign in and sync your documents across multiple devices, including PC, Mac, and mobile platforms, without the strict DRM activation limits typically associated with Adobe Digital Editions, making it easier to access your files anywhere.
