Purchase either a classroom or a single-user license to continue using ROBOTC past the 30-day trial period. Once the purchase is complete, a license ID and password will be sent which you will need to activate the license. ROBOTC can be activated on a single computer for the single user license and a maximum of 12 computers for the classroom license. 

Online
Purchase a single-user or classroom license online. The license ID and password to activate the license will be emailed to the address specified. This can be used to activate a copy of ROBOTC that was previously downloaded.

CD-Rom
Purchase a single-user or classroom license by ordering a CD-ROM version. A license ID and password to activate the license will be printed on the CD-ROM label. This is recommended for schools.

Once ROBOTC is purchased, follow the instructions in Activation Help to activate the software.
