Why does the Security Script Wizard logs contain"0x80070005" exceptions even though the script ran successfully?

Answer

This occurs if the FEM user running the script contains a "." in the username (e.g. "p8.admin").

Error stack generated in Security Script Wizard logs:
Error saving class definition after adding permission: Error 0x80070005 at System.Environment.GetStackTrace(Exception e, Boolean needFileInfo)
at System.Environment.get_StackTrace()

at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)

If there is a username containing a "." then the error can be ignored.
