SQL Server 2008 Setup Error RunDiscoveryAction Failed to retrieve data for this request

If you get this error in your sql setup logs  RunDiscoveryAction “Failed to retrieve data for this request”…

The issue is due to the wrong registry setting for ‘InstalledInstances’. It should be of type multi string(REG_MULTI_SZ). Don’t forget to change this in the Wow6432Node also. After changing the registry settings, the setup routine runs succesfully…

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SQL Server
