Exchange setup failed to install error code 1619

I am upgrading Exchange 2016 CU3 to Exchange 2016 CU9. Updates for Exchange Servers are essential, just like all other systems. Bugs get fixed, and new features get introduced. That’s always great to see. This time the Exchange setup failed, and an error occurs. Let’s have a look at why the error is showing and the solution to it.

Run Command Prompt as administrator. Run the command to start the Exchange Cumulative Update.

E:\>Setup.exe /IAcceptExchangeServerLicenseTerms /Mode:Upgrade
