I was running the uninstallation of a Microsoft Exchange Server 2016 and the server crash and reboot.
After the reboot i try to start the uninstallation again and only got “An incomplete installation was detected. Run setup to complete Exchange Installation.”
When try to run the setup from the installation DVD/ISO it not starts so i search for help and find out that i could start a unattended uninstallation by starting a Command prompt as adminsitrator and go to where the setup.exe file is on the DVD and then run the command:
- Setup.exe /mode:Uninstall /IAcceptExchangeServerLicenseTerms
Then it start running “Welcome to Microsoft Exchange Server 2016 Unattended Setup”.
