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.

1
Confirm the software name

Verify your exact software name to determine if you are using Adobe Acrobat Pro DC or a third-party application named PDF Pro.

2
Locate the full version number

Find your software's full version number, which is usually located by clicking 'Help' > 'About' in the top menu bar.

3
Create a new test file

Create a completely new test PDF document in the recently updated application.

4
Test with the recipient

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.

Accurate Identification: Providing the exact version number rather than simply stating 'latest' is crucial for matching your issue to known bugs from the software developer.
