TI-84 Plus CE Prgm File Transfer Error
« on: May 10, 2017, 11:30:37 pm »
Hi Everyone!

I came across this forum while searching for a solution to an error message I am receiving from TI Connect CE. I've searched for about two hours with no luck. Hoping someone here may be able to help.

I have a TI-84 Plus CE calculator purchased in Jan 2016. I installed updates on the calculator (5.0 to and updated the TI Connect software for Windows today. Since then, I am unable to install program files (.8xk). TI Connect Program Editor only recognizes TI-83 Plus programs and when I drag .8xk files, I receive this error message: Not a program - Sorry. It appears that (file).8xk is not a calculator program. I've tried several types of .8xk files including files from the TI Education site and

I've uninstalled and reinstalled TI Connect twice. I've reset my calculator to default once. Any suggestions would be greatly appreciated.

Thanks in advance,

Apps for the CE are *.8ek files. Programs for the CE are *.8xp files. *.8xk files are apps for the 83+/83+SE/84+/84+SE and are not compatible with the 84+CE.
You'll want to look here for files on ticalc:
And here for files on the TI Education site:
You can also find programs on Cemetech here:
