Prerequisites check error : Configuration Manager requires a dedicated SQL Server instance
Posted On 11 November 2019
After the reinstallation of my test environment, I have been facind an issue during the prerequisites check:
This error is triggered if during the prerequisites check, SCCM detects traces of an existing SCCM installation on the SQL server.
After some thinking, I have found out that the registry key HKLM\SOFTWARE\Microsoft\SMS was still there even if have uninstalled my SCCM the day before.
After deleting this registry key, the prerequisites check went fine.
