Cannot connect to WMI Provider SQL server configuration manager error

Open your CMD prompt as an Administrator and execute the below command (example for SQL server 2017 )

C:\WINDOWS\system32>cd C:\Program Files (x86)\Microsoft SQL Server\140\Shared

now, execute

mofcomp sqlmgmproviderxpsp2up.mof

Output should be below

Now you should be able to open SQL server configuration manager.

For other older versions, location for "cd" command must be

SQL 2008: C:\Program Files (x86)\Microsoft SQL Server\100\Shared\
SQL 2012: C:\Program Files (x86)\Microsoft SQL Server\110\Shared\
SQL 2014: C:\Program Files (x86)\Microsoft SQL Server\120\Shared\
SQL 2017: C:\Program Files (x86)\Microsoft SQL Server\140\Shared\
SQL 2019: C:\Program Files (x86)\Microsoft SQL Server\150\Shared\

Cause of error:

This problem occurs because the WMI provider is removed when you uninstall an instance of SQL Server. The 32-bit instance and the 64-bit instance of SQL Server share the same WMI configuration file. This file is located in the %programfiles(x86)% folder.

OR

If above solution doesn't work you can also uninstall the instance and reinstall a fresh instance. 

When you try to run above commands in CMD, always open it in Administrative mode.

  cd C:\Program Files (x86)\Microsoft SQL Server\110\Shared
  cd C:\Program Files (x86)\Microsoft SQL Server\140\Shared
  mofcomp sqlmgmproviderxpsp2up.mof

Thanks
