NOTE: There is a known bug in the licensing for National Instruments software (including the software that is required to support the cRIO.) The serial numbers included in the software kit will fail to activate at this time. The solution to this bug is to either run in Evaluation Mode temporarily as the bug will be fixed by 15 Jan 2010, or a working serial number will be posted on the Mandatory LabVIEW update page, linked below.
Currently we are waiting for the update.
