Software updates are listed on the
FIRST website, leading you to the
mandatory update of the driver station software. This is either a new install on a new development laptop, or an upgrade to an existing laptop or the classmate.
HOWEVER, the update will break the camera display on the dashboard (assuming it was ever working). So, when you get to the install screen that lists the software, click on the dashboard option and choose to NOT install it on the computer. This will cause the "install" to uninstall the software. Then rerun the install again.
If you did it right, the dashboard should show the camera images automagically.
