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

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. Can you help? 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 try to follow the Microsoft documentation for this upgrade and within a few minutes I have 10 or more tabs open with all different information and guides – This is not helpful.
