Hi,
you could manually add the required entries, first create a backup of your registry (no problems to be expected, but always recommended) and afterwards create the key(s) HKEY_CLASSES_ROOT\Word.Document.12\shell\Printto\command
with the default entry being "C:\Program Files (x86)\Microsoft Office\Root\Office16\WINWORD.EXE" /j "%1" "%2"
as on the screenshot below (German OS though):
Best regards,
Robin
