So, I'm setting up my calculator for a test and I'm trying to put programs or apps into my calculator using ti connect and when i go to the programs in the calculator, it says error:archived

keep in mind i have a ti-84 plus and im running windows vista, i updated the calc to the latest firmware/os which was 2.43

i tried unarchiving but it didnt do anything, and right now im deleting the apps through ti connect manually

also, anyone know how many programs I can store on this thing?

and im also looking for a program that calculates exponential growth and decay

any help is appreciated
