Hello,

sorry for the late reply.

PDF/A is not a separate command but a PDF standard for long-term archiving (ISO 19005). Many authorities and archives require it. In PDF24 you choose it when saving:

1. Print the document on the PDF24 printer or open it in the PDF24 Creator.
2. Click Save as... and select the format PDF.
3. Set PDF standard to the PDF/A version you need (PDF/A-1, PDF/A-2, PDF/A-3 ...) and save.

For print jobs that should always become PDF/A automatically, create an output profile with this PDF standard and select it as profile of the automatic saving of the PDF printer. Since version 11.31.0 a printed document can also request PDF/A itself with the control code @@ca:1@@: https://creator.pdf24.org/manual/11/#62-control-codes-in-printed-documents

Existing PDF files can also be converted online: https://tools.pdf24.org/en/pdf-to-pdfa

To the original question: if a PDF/A file from the current PDF24 version is still reported as invalid on one computer, please check it with https://tools.pdf24.org/en/validate-pdfa (it lists every rule that is not met).
