I've had 5 clients this week tell me that they cannot open the .pdf's I have created in Corel Draw. I have tried the Save As function, the Export Function, and the Publish to PDF function, and there doesn't seem to be a difference for the clients.
Other posts have suggested using a different program to open the files, but I have not control over what a client uses to open them.
I am running Corel Draw 2017 ver. 184.108.40.2069, on Windows 10 Pro ver. 1709
what are your pdf settings?
What preset are you using in the publish to pdf dialog?
What are they trying to read the PDF with?
I have no idea what they are trying to open them with, but it seems to me that it shouldn't matter. The point of .pdfs is for them to be opened by anyone, right? One standard format for everyone?
Acrobat reader would be the standard test as it's free and Adobe. Can you post a PDF file or a link to download a PDF file that fails for your client? Sometimes using fonts that are not licensed for embedding causes issues.
