Install failing on CleanWMIRepository

[unni nair]

I am trying to install JustTrace and install failing on CleanWMIRepository with following exception, I am using Win 7 but just code and just mock installed fine.

Calling custom action InstallerCustomCommands!InstallerCustomCommands.CustomActions.CleanWMIRepository
+CleanWMIRepository
Not found
   at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
   at System.Management.ManagementObject.Initialize(Boolean getObject)
   at System.Management.ManagementBaseObject.get_ClassName()
   at System.Management.ManagementClass.GetSubclasses(EnumerationOptions options)
   at System.Management.ManagementClass.GetSubclasses()
   at InstallerCustomCommands.CustomActions.CleanWMIRepository(Session session)
-CleanWMIRepository
CustomAction CleanWMIRepository returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
Action ended 23:07:28: InstallFinalize. Return value 3.

Thanks

Hello,

This error may indicate that the WMI repository on your system is corrupted.

To verify if this is the case, bring Start Menu, search for "wbemtest" and run it. Press "Connect...". In the dialog, type "root\WMI" (without the quotes) in the Namespace field and press Connect. Press "Enum Classes". In the dialog enter EventTrace and press OK.

If this query gives the same error  as JustTrace installer, then the WMI repository is corrupted. I suggest you check this article for steps to verify and repair the WMI repository.

If the tool successfully executes the query, please tell me, so that we can pursue other options for fixing this issue.

Kind regards,
Todor
