System.Management.ManagementException: Invalid class

[Guest LuChuanhua]

Hello.

 

When I launch a application with "PhotonControl", I got following error message:

 

 

 

PhotonControl Error

 

Failed to query processes. Exception:

 

System.Managemnt.ManagementException: Invalid class

 

at System.Management.ManagementException.ThrowWithException(ManagementStatus.errorCode)

 

at System.Management.ManagementObject.Get()

 

at PhotonControl.Helper.ProcessInfo..ctor(Process process)

 

at PhotonControl.Helper.PhotonHandler.GetActiveProcesses(Int 32& serviceCount, Int32& appCount, Int64& memory)

 

 

 

When I go to Manage->Services and Applications->WMI Control->Properties, I can see following dialog:

 

 

 

Failed to initialize all required WMI classes.

 

Win32_Processor: WMI: Invalid class

 

Win32_WMISetting: WMI: Invalid class

 

Security information: Successful

 

Win32_OperatingSystem: WMI: Invalid class

 

 

 

I think the PhotonControl Error is caused by this. Is there any way to fix this problem?

 

 

PS: I don't have a backup of the WMI.
