Azure Active Directory Connect error after upgrading Windows Server 2012R2 to 2019

I have upgraded my Windows server from 2012R2 to 2019 and am trying to get the Azure AD Connect V1.6 upgraded to it can sync with Azure AD (Entra ID) again.

What I have done:

I downloaded the Entra Connect sync tool, from the link in Directory sync status page on Office365 portal. After installing, I launch Azure AD Connect, I must click on Upgrade as it prompts me to, then I get an error: "Upgrade cannot proceed because the Azure Active Directory is missing."

Is anyone able to provide some insight and a way forward to this?

I tried to follow the Microsoft documentation for this upgrade and within a few minutes I had 10 or more tabs open with all different information and guides - This is not helpful.

I was recommended (from the learn.microsoft.com forum) to:

Uninstall the existing Azure AD Connect.
Perform a clean install of recent version of Azure AD Connect.

I did it.

.......

I uninstalled Azure AD Connect. That was version 2.2.8.

I still see version 1.6.16.0 "Microsoft Azure AD Connect synchronization services" is still showing in Apps & Features. The Uninstall & Modify buttons are greyed out.

I tried to reinstall Azure AD Connect, Version 2.2.8, got a new error:

"An error has occurred on the Root page, preventing Azure AD Connect from continuing. To protect your existing data, the wizard must be closed."

InvalidOperationException

Service ADSync was not found on computer .*

What to do next:

Contact Microsoft using the MSDN Forums site where you can post a message to the Azure Active

Directory forum. Be sure to include relevant information regarding how the error occurred.

Otherwise, check the log for more detailed information:
