Request an Activation Count Reset from Adobe Support
Contact official Adobe customer support to manually reset your activation count, which clears the device limit error.
Deactivating Acrobat installations from old computers may not immediately clear the activation limit on Adobe's servers. To fix this, an official support agent must reset the count for your serial number.
Navigate to the official Adobe contact page at helpx.adobe.com/contact.html or the phone support page at helpx.adobe.com/contact/phone.html.
Log in using the Adobe ID that is associated with your Adobe Acrobat 2017 license to verify your identity.
Open a live chat or call the support number, and explicitly ask the representative for an 'activation count reset' for your Acrobat 2017 serial number.

Manually Deactivate Acrobat on Previous Devices
If you still have access to the old computer where Acrobat 2017 was installed, you can attempt to release the license manually.
Use WPS PDF to Edit and Manage Documents Without Activation Limits
Instead of dealing with strict device limits and activation errors, try WPS Office. It includes a powerful, built-in PDF editor that allows you to view, edit, convert, and sign PDF documents effortlessly across multiple devices without complex serial number limitations.
- 1. Download and Install: Download WPS Office for free from the official website and run the installer.
- 2. Open the PDF Editor: Launch WPS Office and click on the 'PDF' tab on the home screen.
- 3. Import Your Document: Click 'Open' to browse your computer and import your existing PDF files.
- 4. Edit and Save: Use the top toolbar to edit text, add comments, sign the document, or convert it to another Office format.

Frequently Asked Questions

How many computers can I install Adobe Acrobat 2017 on?
A standard single-user license for Adobe Acrobat 2017 allows you to install the software on up to two computers (e.g., a desktop and a laptop), but you are only permitted to use the software on one computer at a time.

How do I know if someone offering help in the Adobe forums is a legitimate employee?
Official Adobe employees have a verified 'Adobe Employee' tag below their username in the community forums. They will only direct you to official adobe.com contact channels and will never ask to communicate via Skype or non-Adobe email addresses.
