Hi guys, had some great for an earlier question, getting the below error
I have updated .Net Framework 4.8
I have run and rebooted in between the following steps separately
Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareSchema
Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareAD
Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareAllDomains
