I am having the same problem...I have QB 2020 Desktop Pro and can NOT save my invoices as a PDF in order to be able to email them to my customers at a later date. It worked perfect on my old computer that was running Windows 10, but after transferring my QB to a new computer with WINDOWS 11, it won't work.  Says missing component. I tried to use the QB HUB TOOL but to no avail...this is very frustrating.
