The PDF generated from that file works fine.

I’ll try to find out where I do something special.

I suspect either keywords or encryption.

It was keywords.
When I remove the PDF Keywords I get rid of that message.
Which is weird, since I can’t see the keywords anywhere in the Explorer.

I’ll ask the client if they actually use the keywords.

Thanks for looking into it.
