A few possible issues.
(1) If you can successfully create PDF via the Adobe PDF PostScript printer driver instance to some locations, but not others, it implies that the file and directory security settings are setup such that you are restricted as to where you can create, modify, and/or delete files and directories. Out of the box, most Windows systems give the user by default Administrator privileges on your local system. It may be that however your system was setup, you were granted much more restricted access and that many system areas on your system were protected against your access and/or modification.
(2) Office 2013 has a fairly poor “Save as PDF” feature built in. But if you have Acrobat installed, you should also have access to the “Create Adobe PDF” and/or “Save as Adobe PDF” which Acrobat adds to Office. Such PDF is much higher quality than Microsoft's built in PDF and even the printing to PDF via the Adobe PDF PostScript printer driver instance, preserving colors and live transparency. However, you might encounter similar permissions issues depending upon where in your file system you are attempting to create the PDF file.
