print to PDF with 11.0 fails with "invalid handle" from ALL applicaitons and "print test page"

As I said the problem is with ANY (repeat ***ANY **) application which you can print from i.e. nothing prints to Adobe PDF:

- Pick any application (say Adobe Acrobat for example)

- open any document

- select print

- choose "Adobe PDF" from the list of installed printers

- hit print

- silently refuses to print

Even if you go to Control Panel -> Printers -> Printer Properties and select Adobe PDF and then select "Print Test Page" it refuses to print but at least this time it gives you the error message "Invalid Handle"

In other words the application I am printing from is irrelevant: the problem is with the Adobe PDF print driver!

As an aside the problem (which was in the print driver) has been fixed!

As another question:

@jane-e said: "Print to PDF is usually the last resort for making a PDF. It is not the preferred method if another is available. As Willi said, list the applications."

How are you supposed to create PDFs from applications such as word processor documents if not for Print to PDF???

1: Windows 10

2: ALL applications including print test page from Printer Properties

Thanks
