Is there anyway possible for me to transfer my license for my texas instrument ti-nspire calculator program on my other desktop computer to my laptop? If so, could you run me through the steps?

To transfer the operating system to the handheld, connect your handheld and computer with a USB Connection Cable and use TI-Nspire™ Teacher Software with TI-SmartView™ or TI?Nspire CX Student Software (Windows® / Mac®).
This is the link that will download the OS (it's free) to your computer:

You must be connected to the internet while installing, because the software validates the license with the Texas Instruments website. It probably creates a unique ID that links the license number, and your computer so that you may not install it on more than one computer.

The standalone version of the OS for the TI84Plus/TI84Plus SE are not for TI-Nspire with TI84 keyboard. The 94 Plus part of the TI-Nspire is updated when you update the OS of the TI-Nspire. The version numbers are different.
To update you TI84 portion of the TI-Nspire, update the OS for the TI-Nspire. Thy are now at Version 3.2.3.1233

Maybe the file is missing, or there is a defect on the disk. I suggest you go the education.ti.com website and download the trial software from there. Install it on your computer and validate it with the license that came with your calculator.

You get that message if you own a license for the TINspire Software, and you installed it on one computer, but now you are trying to use it on another computer.Apparently a single license can only be installed and validated once with a TINspire and the computer. I have had the same problem and have not found a way to revoke the license on the old computer and revalidate it on the new computer.

Whay would you want to go through the hassle of writing a program to solve to solve a quadratic equation`The calculator has two buit-in command to do just that. It has Solve and cSolve (for complex solutions).

Open a calculator sheet, and on the command line, type in solve(ax^2+bx+c=0, x), press ENTER and wait for the solutions

Hello,
If you remove battery door, the TINspire CAS cannot be turned ON.
You may try to reset the unit by pressing the reset button on the back of the unit. If that does not solve the problem, you may try to reinstall or update the OS.

Anyway, here is what the Texas Instruments Knowledge Base has to say about reinstalling the OS. Hope it helps.

What steps are required to reinstall the TI-Nspire family operating system?

To reload the device’s OS using a computer with TI-Nspire Computer Link:
• Connect the TI-Nspire device (with the Nspire keypad) to the computer using the USB Standard A to Mini B cable.

• Either drag the OS file (available in the ‘downloads’ area at education.ti.com) onto the TI-Nspire File Browser portion of the window, or click Tools -> Install OS.
To reload the device’s OS using another TI-Nspire or TI-Nspire CAS device:

• On the sending unit, access the document chooser by pressing [Home] [7]. Once in the document chooser, press [Menu] and choose 9:Send OS…
NOTE: Users can only send an OS to a unit of the same model. Users cannot send an OS from a TI-Nspire to a TI-Nspire CAS.
