Welcome to the forum. I don't remember ever seeing that particular error message before, but you might try printing to pdf instead of saving as. See #7 at Frequently Asked Forum Questions for more information.
for the quick suggestion, I will try that and let you know if the error continue to popup.
Hi Glenn ,
we try "print to PDF" but we are still getting the same error .
also , I notice that the user doesn't have any adobe software on the PC , his using Nitro. not sure if that might be the issue.
