WMI Errors

How can i catch errors from wmi query?

Look in the help file at Obj/COM Reference, scroll down near the bottom, there is a COM error handler. For lighter-weight handling, most WMI queries return a collection object. A test like this usually catches errors in a simplistic yes/no fashion:

If IsObj($colResults) Then
     ; ... it worked
     For $oResult In $colResults
          ; Do stuff
    ; ... it failed
    MsgBox(16, "Error", "WMI query did not return an object.")
