VBA to set Content controls as non printing

[thedoost]

You might be right, Greg, but weird that it would work initially with the same printer popup. I hope you're right.
I just tried copying the code in but I get a Compile error:
"The code in this project must be updated for use on 64-bit systems. Please review and update Declare statements and then mark them with the PtrSafe attribute."
Any idea what I can do to fix it? It highlights the word "Sub" in the third line of code if that helps.
