Sorry about that. We recently made some minor changes to our website structure, which is why that link was 404’ing. I’ve updated the link in the footer to reflect it. The page you were trying to access can now be found at www.vexrobotics.com/vexedr/products/firmware
However, you can not actually download ROBOTC from that page. The firmware page is used to download the VEXnet Firmware Upgrade Utility. ROBOTC can be downloaded after logging into your vexrobotics.com account, and clicking the “Software Downloads” Tab.
