WMI path and C# Question

[Henry]

Below is the code I am trying to use in a console application, each time I
run it I get an Management error Illegal Class error. I have traced the
error to the \"Win32_Process \" line, apparently the wmi path is incorrect.
Tried to run the app on both xp and vista with the same error. Could
someone suggest how I might correct this wmi path variable???

Thanks

Henry
