Error Preflight when saving as PDF/A on Windows 11

Report · Feb 09, 2023

When trying to save as a PDF/A file in Acrobat Pro DC it throws an error.

Assertion failed in file D:\T\Plugins\Preflight\src_pdfToolbox\pdfInspektorBatch\_Imp\PIBatchAVConversion.cpp, line #566:"CPreflightDlgManager::getDefaultPRCs(state,progbar)"

I been in contact with support who confirms this is a bug and given me several workarounds to try which we have tried without success. However I can't find any more information on the issue and the issue is urgent. This does not occur on Windows 10 but on Windows 11.

We have tried:

Reinstalling, repairing and updating
Installing an older version
Unchecked "Enable Protected Mode At Startup" and "Run in Appcontainer"
Deleting registry keys Adobe Acrobat, Acrobat Arm, Acrobat Distiller, PDF settings.

I have tried on 2 different machines with Acrobat Pro and Windows 11 and it throws the same error.

On the 2nd machine, unchecking "Enable protected mode at startup" enables me to save the PDF as a PDF/A but sometimes gives the error "Document has been saved, but could not be converted according to the selected standard profile: Convert to PDF/A".

Is this being worked on by Adobe? Has anyone found a solution?

Update:

Not sure what does it, and its not a complete solve, but it does save some files as PDF/A without errors now with

a new installation
updating
deleting these keys in Hkey current user in regedit: Adobe Acrobat, Acrobat Arm, Acrobat Distiller, PDF settings.
And maybe most importantly unchecking "Enable protected mode at startup", restarting, then checking that option again, and restarting.

It works for some documents, but some still gives an error.

A user of mine was getting the following error messages when trying to save as a PDF/A document from Acrobat. Like shown in this YouTube video:

Similarly to the issue described in this article:

https://community.adobe.com/t5/acrobat-discussions/error-preflight-when-saving-as-pdf-a-on-windows-1...

The recommendation here did not resolved the issue:
preflight error_ unable to copy the user specific settings - then crashes
https://community.adobe.com/t5/acrobat-discussions/preflight-error-unable-to-copy-the-user-specific-...

The solution in this article worked:
Preflight Error: Unable to load user preferences

You can also try what is expressed in this article to see if Acrobat can fix any errors or problems when saving as PDF/A:
