I had to reinstall Windows 8.1 on my computer. Before I was able to edit and insert PDFs with no trouble. I was able to insert PDF files into my Microsoft Publisher easily. Now, I can't either edit or insert PDF files as I did before. All it will let me do is read the files. What program do I need to download to be able to edit, copy and inssert PDF files once again.
Reinstall / update your MS Office applications (note that Acrobat's PDFMaker (for PDF generation from MS Office applications) does not support Publisher.
With a "good" install of Publisher you can use the in-built Microsoft routine to create PDF. Could be better but it works.
Or, purchase and install Acrobat (Standard or Pro) to get the Adobe PDF virtual printer. Any application that can "file - print" to a paper printer can print to PDF using this virtual printer.
