Run the Adobe Licensing Repair Tool
The most direct way to fix corrupted licensing data that causes Acrobat to revert to trial mode.
Corrupted licensing files can persist even after reinstalling Acrobat. Adobe provides a dedicated Licensing Repair Tool to safely reset these internal activation states.
Navigate to the official Adobe Support page to download the Licensing Repair Tool.
Extract the downloaded file and run the tool with administrative privileges to allow it to modify local licensing cache files.
Once the tool completes the repair process, restart your system and launch Acrobat 2017 to sign in and activate normally.
Perform OS-Specific Licensing Troubleshooting
Follow Adobe's official guidance for resolving underlying 'Licensing for this product has stopped working' errors on macOS or Windows.

Frequently Asked Questions
Why does Acrobat 2017 keep asking me to sign in?
This usually happens when the local licensing data on your computer becomes corrupted, or when system permissions prevent Acrobat from reading the activation files correctly.
Will reinstalling Acrobat fix the trial mode issue?
Often, a standard uninstallation leaves behind the corrupted licensing cache. You typically must use the Licensing Repair Tool or manually clear the FlexNet licensing folders before reinstalling.
Where can I find the FlexNet folder on Windows?
On Windows, the FlexNet folder is typically located in C:\ProgramData\FLEXnet. You may need to enable 'Show hidden files and folders' in Windows Explorer under the View tab to see it.
Can a firewall cause Acrobat activation to fail?
Yes, if your firewall blocks Acrobat from communicating with Adobe's activation servers, it may revert to trial mode. Ensure that Acrobat is allowed through your system and network firewalls.
