While launching SQL Server Configuration Manager on one of my machine, I got below error

Here is the text of the error message:

—————————
SQL Server Configuration Manager
—————————
Cannot connect to WMI provider. You do not have permission or the server is unreachable. Note that you can only manage SQL Server 2005 and later servers with SQL Server Configuration Manager.
Invalid class [0x80041010]
—————————
OK  
—————————

There might be various reason for this error. In this case our actual problem is “Invalid class” which I have highlighted above. I have looked further and found that below is the solution for me. Same solution also works for Invalid namespace [0x8004100e] error also. 

C:\WINDOWS\system32>mofcomp "C:\Program Files (x86)\Microsoft SQL Server\120\Shared\sqlmgmproviderxpsp2up.mof"
Microsoft (R) MOF Compiler Version 6.3.9600.16384

Parsing MOF file: C:\Program Files (x86)\Microsoft SQL Server\120\Shared\sqlmgmproviderxpsp2up.mof
MOF file has been successfully parsed
Storing data in the repository…
Done!

MofComp is a command line utility to compile MOF (Managed Object Format) files and store the data in WMI repository. The MOF Compiler is available in the %Windir%\System32\wbem directory. So if you are getting “‘mofcomp’ is not recognized as an internal or external command then try changing current directory from command prompt to %Windir%\System32\wbem

Also note that in mof file on my machine is under 120 folder. Depends on SQL version installed, you may have it in different folder. The value of that number depends on the version of SQL Server.

Hope this helps.
