I get the error “Failed to compile the Managed Object Format” when the IGSS installer reaches the SQL server installation.
This turns out to be related to a corrupt WMI repository – and the fix is quite easy.
Run the following commands in the C:\Windows\system32\ folder.
WMI repository is INCONSISTENT
WMI repository salvage failed
Error code: 0x8007041B
Description: A stop control has been sent to a service that
other running services are dependent on.
WMI repository has been salvaged
As you can see, you have to run it more than once – but it eventually fixes the problem. Then you click the Retry button in the above error message.
