Work-around solution found on another forum:
Control panel then Settings then Add Printer
Choose "Add a local printer". Click on "Create a new port". Use Local Port.
Next dialogue box is "Enter a Port Name."
Type in the path to the printer: \\(computer name)\(printer name).
This worked for me after MANY, MANY hours of trying to do it by the "book"
After deleting the server/printer entry from
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers\Client Side Rendering Print Provider\Servers and
I was able to re-install my printers.
