So basically it's the PDF Print driver. Running it, I get:
Installing Amyuni PDF printer driver Error Code: 5 Access is denied.
------------------------------------------------------------------------------------ Installing Amyuni PDF printer Error Code: 5 Access is denied.
------------------------------------------------------------------------------------ Printer setup failed Error Code: 5 Access is denied.
------------------------------------------------------------------------------------
Googling, the only fix I've fouind that works is to delete atpdf500.cat and amyuni.inf. I can then install (manually) the PDF converter. It's installed. But as soon as I run the quicken installer, it puts back those files, runs the install, and then fails. Any suggestions? Admin, run as admin, Windows 10...
