- not provided
- Scenario
- Creating and sending PDF files to other users via email or other methods after installing a software update.
- Observed behavior

Identify Software Version and Diagnose File Integrity
Verify the exact PDF software version being used and isolate whether the update is causing document corruption during file creation or transmission.
Software updates can occasionally introduce bugs that corrupt file outputs or change default compatibility settings. To find a fix, you must first accurately identify your software version and test the file integrity.
Verify your exact software name to determine if you are using Adobe Acrobat Pro DC or a third-party application named PDF Pro.
Find your software's full version number, which is usually located by clicking 'Help' > 'About' in the top menu bar.
Create a completely new test PDF document in the recently updated application.
Send both the new test PDF and an older, known-good PDF to the recipient to determine if the issue is with the new file creation process or the recipient's system.
Use Alternative File Transmission Methods
Bypass potential email attachment corruption by changing how the file is packaged and sent.
Create and Share Compatible PDFs with WPS Office
If your current PDF application is causing compatibility errors after an update, WPS Office provides a highly stable, built-in PDF reader and editor. It ensures files are created with standard encoding so recipients can open them on any device without failure.

- 3. Create or open files: Click 'Open' to import your existing documents or choose 'Create PDF' to generate a fresh file.

Open Adobe Acrobat Pro, click on 'Help' in the upper menu bar, and select 'About Adobe Acrobat Pro'. A dialog box will appear displaying the full version number.
Is PDF Pro the same as Adobe Acrobat Pro?
