Fix Adobe Acrobat Send for Signature Stuck in File Selection Loop
Question details
Users are unable to send PDF documents for signature because the application repeatedly loops back to the file and recipient selection screen.

- Product
- Adobe Acrobat
- Device & OS
- Windows 10, Windows Server
- Scenario
- Attempting to send a PDF document for electronic signature to specific recipients.
- Observed behavior
- The application fails to proceed after selecting files and recipients, looping back to the selection screen or displaying a generic error message, particularly after an account email update.
Ensure you have a stable internet connection and verify that your software account credentials are up to date, especially if you recently changed your account email address.
Restart System and Verify Acrobat Version
A simple system reboot and software update check can resolve temporary cache glitches causing the signature loop.
Software updates often contain patches for known authentication and interface bugs. Ensuring your version is current can resolve loops during the signature process.
Close Adobe Acrobat completely, ensure no background processes are running, and restart your Windows computer or server.
Open Adobe Acrobat, navigate to the 'Help' menu on the top toolbar, and select 'Check for Updates'.
Follow the on-screen prompts to install any available updates, then restart Acrobat and attempt to send the PDF for signature again.

Test via Web Browser Interface
Bypassing the desktop application helps determine if the issue is localized to your installed software or if it is an account-level error.

Frequently Asked Questions
Why does my PDF software loop when requesting a signature?
This usually occurs due to an authentication error, an outdated desktop software version, or a background sync issue with your account credentials, which often happens immediately after an email address change.
Can I sign a PDF if the desktop app continues to fail?
Yes, you can bypass the desktop application entirely by logging into the cloud or web-based version of your PDF service, or by using a lightweight alternative like WPS PDF to sign the document locally.
How do I fix the 'An error has occurred' message when signing?
This generic error is frequently linked to mismatched account details. Verify your updated email and password, log out of the application completely, and log back in. If it persists, checking for a software update or contacting support is recommended.
Are electronic signatures added via WPS PDF compatible with other software?
Yes. When you sign and save a document using WPS PDF, the resulting file is a standard PDF format that can be opened, viewed, and verified in other major PDF readers without any compatibility issues.
