Solution 39257: Correcting the Error Message Waiting...Please Install Calculator Software Now on a TI-84 Plus Family Calculator.

How do I correct the Error Waiting...Please Install Calculator Software Now message on my TI-84 Plus family calculator?

If an operating system (OS) update fails or is interrupted, the calculator will be in an inoperable state with the message Waiting...Please install calculator software now. The most common cause of a transfer being interrupted is updating the operating system on a calculator with low batteries or charge.

Please Note: If TI Connect CE software is not already installed please do not have your calculator plugged into your computer during the download and installation of TI Connect CE.

In order to install the software please follow these steps:
