This problem also occurs if you uninstall the 32-bit instance, and you then open SQL Server Configuration Manager.

Cause

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.

Workaround

To work around this problem, open a command prompt, type the following command, and then press ENTER:

mofcomp "%programfiles(x86)%\Microsoft SQL Server\number\Shared\sqlmgmproviderxpsp2up.mof"

Note For this command to succeed, the Sqlmgmproviderxpsp2up.mof file must be present in the %programfiles(x86)%\Microsoft SQL Server\number\Shared folder.

The value of number depends on the version of SQL Server:nnn

Microsoft SQL Server 2012	110
Microsoft SQL Server 2008 R2	100
Microsoft SQL Server 2008	100
Microsoft SQL Server 2005	90

After you run the Mofcomp tool, restart the WMI service for the changes to take effect. The service name is Windows management Instrumentation. 

after run this query in command prompt now am open configuration manager it opens with no issue
