  Problem(Abstract)
  When installing, upgrading, starting or stopping an IBM Cognos Express component the following error appears:
  SDK-ERR-0079 Xcelerator services failed to restart properly: SDK-ERR-0141 A call to WMIC command failed.
  Cause
  WMIC is either not installed or is not configured correctly.
  Diagnosing the problem
  To confirm if the issue is with the WMI / WMIC itself, please go through the following to confirm.
  1. Launch a command prompt window.
  2. Type wmic and press enter
  3. Enter the command "service where Name="IBM Cognos Express" get Name/VALUE"
  If Cognos Express is installed a working system should return:
  Name=IBM Cognos Express
  On a broken system you will see an error like this:
  Node - computername
  ERROR:
  Description = Invalid class
  If you receive the following error, please see IBM Technote : 1433767 on the "Unable to Stop the Service IBM Cognos Express" link below.
  ERROR:
  Code = 0x8004100e
  Description = Invalid namespace
  Facility = WMI
  Please note: If you are using Windows 2003 server you may need to install an optional Windows component called "WMI Windows Installer Provider". This component can be installed through "Add/Remove Windows Components" from the "Management and Monitoring Tools" group. For further information please see the "Installing optional Windows 2003 WMI components." link below.
  Resolving the problem
  Please note: This issue is an issue with Microsoft Windows itself rather than the IBM Cognos Express product.
  Please use the following as a guide to locating the error that the WMI / WMIC is generating. Once this is located please refer this particular error to your IT personnel and/or Microsoft to correct.
  When dealing with general WMI troubleshooting, the first thing to do is to test the WMI service. The quickest way to do this is via the WMI Control snap-in:
  1) Click Start, click Run, type wmimgmt.msc, and then click OK.
  2) Right-click WMI Control (Local), and then click Properties.
  3) If the WMI service is configured correctly, the WMI Control will connect to WMI and display the Properties dialog box.
  4) On the General tab, you should see information about the operating system and the version of WMI. If it shows any errors or is unable to display the information, document the message seen (or capture a screenshot).
