Files are either damaged or unsupported.

[Michael1]

Hi

Every time I edit a PDF, then save the PDF, I cannot reopen it and I get this message "could not be opened because its an unsupported file type or damaged". Nitro lets me edit then save, but once I try to reopen I get this message. Ive tried a reinstall, tried on a different machine but the same error each time.

Please could someone help

 

Thanks

While I'm not totally sure, it seems like you could possibly be trying to edit a Dynamic Form / XFA document, which Nitro has issues with.  If you go to File, and see the Creator and/or Producer on the right hand side is Adobe LiveCycle, that's a good indication of this.  There's unfortunately nothing you can do in this case.

If this happens with every PDF, and those PDFs aren't all forms, it's worth reporting the issue if you can.

Here's the download page to make sure you're on the latest version of Nitro: https://www.gonitro.com/nps/product-details/downloads
