    Follow these steps, rebooting after EACH step and running from an ELEVATED PROMPT.

    Install .net 4.8:

    Run each step separately: ( not absolutely required in a single forest architecture. I always recommend it though. Otherwise run setup and these steps will be done automatically if you have the correct perms:
    Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareSchema
    Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareAD
    Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareAllDomains

    Then install CU20:

    then install the post CU20 security patch
