Need to be careful when using RUN. If the KiX scipt finishes before the command you run, it has the potential to throw an exception. This can vary by OS as well with wintendos the most vulnerable. The better way is not to run it at all from the logon and to simply use the logon script to push it to the RunOnce reg key.
