Either way I think it should be bolded on the NI link and add:
This software is the first mandatory update for the LabVIEW portion of the FIRST Robotics Competition Software 2009. You MUST install this update in order to compete in the FIRST Robotics Competition. THIS MUST BE INSTALLED IN CONJUNCTION WITH THE FRC VERSION OF 8.5 THAT CAME ON THE DVD in the KOP, AND NOT ON THE PREVIOUSLY AVAILABLE VERSION 8.5.1 FROM THE NI FTP SITE!
FIRST has already updated their control system page to reflect this.
We will also be updating the download page on ni.com to reiterate this early this week. The LabVIEWFRCUpdate1.0.zip is only to be installed after installing the LabVIEW FRC Package DVD shipping with the KOP.
