I am trying to buy a single license key for the student software ti-nspire cx cas, but have only been linked to websites with a minimum of 10. To locate the product ID information for your TI software, you need the activitation card that comes in the CD box. The card is located on the left-hand side of the box and has serial and license numbers you will need during registration.

• User friendly CAS Software for PC & Mac (Win XP/Vista/7/8/8.1/10 32&64 bit, MAC from OS X 10.4) • Compatible with other devices in the classroom (PC, Nspire navigator system, Nspire docking station, beamer etc.). Further information: Further information: Downloads: Downloads: Downloads: • TI-Nspire™ CAS Software, ESD licence versions: (ESD=Electronic Software Distribution) Please contact us for orders and any questions on these and other licences. • Single use licence = licence for one workstation (either at school or at home) • Multi-use licence (volume) = licence for several workstations (e.g. For notebook carts). Only the number of workstations purchased can be installed.

• School network licence (concurrent) = licence for several workstations (e.g. In the computer room). The licence can be installed on as many computers as desired. However, only the number of licences purchased by the school can be used simultaneously. Example: A school has 50 computers and has purchased a licence for 10 computers. The licence can be installed on all 50 computers, but only 10 computers can work with the Software at the same time.

• Multi-use licences and school network licences can be purchased as permanent licences (no time limit) or as a subscription licence (licence for 1 year=365 days). Renewal is not automatic!

I was wondering if there was any way to get the Ti-nspire CAS software for free? I used the CAS software for learning how to program certain math concepts (quadratic formula, Pythagorean theorem). I used time-stopper, but I accidentally opened a file, which opened the actual program and made it expire. I used Revo Uninstaller to delete all keys, but when I re-installed the software was still expired. I have also tried downloading a previous version from, but it didn't work either.

Should I contact TI? I threw away the box with the serial number, and I don't have the receipt either. I would purchase the product, but as a high school student, I don't have that type of money.
