At the beginning of the season, our team here at Clarke County High School recieved RobotC 1.40 on cd, with an activation code. Not knowing quite what was going on, we installed it and did not activate it. Shortly thereafter, having had a few problems such as joysticks not working, servos not working, and general irritation, I checked around for updates, found I think 1.44, and have since gotten up to 1.46 and have fixed our problems with joysticks and servos, but another serious issue has come to head.
Our 30-day trial period is up as of today. The new installations did not update the trial period to 365 days as we had expected, and we didn't notice the diminishing trial period until today, when it was too late. We tried unistalling the software, installing it from the cd, and activating it, but no dice.

Bottom line: our trial period of RobotC is up, and we need it to work on this one computer. How can we extend/eliminate the trial period?

Activate ROBOTC 1.46 with the number that is included with your kit on the CD sleeve. This will get rid of the trial period. This is good for up to three machines.

If you are getting an "error code 7", contact support@robotc.net with your LicenseID, and we can take care of the issue ASAP.

Thanks.

Does that mean it would be legal for me to use the same licence for my laptop (which I carry around to work) and my desktop (where I spend my leisure time tinkering with LEGO Mindstorms)?

I believe it is I asked the very same question many months ago and got this answer:
