Resolution

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.

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"

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

The number part of the path differs due to your version of SQL Server:

  • Microsoft SQL Server 2012: 110
  • Microsoft SQL Server 2008 a Microsoft SQL Server 2008 R2: 100
  • Microsoft SQL Server 2005: 90

You need to restart your computer after executing the command. For more information, go to this article.
