You can verify that Arbortext Publishing Engine is running under the Arbortext Publishing Engine user account. The Arbortext Diagnostics utility is a program available on Windows that displays tracing information. You can launch it from the Arbortext Diagnostics shortcut in your PTC program group. The Arbortext Diagnostics window contains the Module List tab that displays the Arbortext PE sub-process information and the Trace Log tab that displays tracing output. The Module List panel should display the Arbortext Publishing Engine user account name instead of SYSTEM.
