Every steps to install notefolio for your ti 84 plus (computer and calc side).
Very detailed article !
If you tried to install notefolio, you should have noticed that ,notefolio is not easy to set up..
That's a shame as notefolio is an official Texas Instrument application but I will help you to set notefolio up correctly.
First thing you need to know is that :
YOU MUST INSTALL TICONNECT TO GET NOTEFOLIO WORKING !!!!
First you need to download ticonnect.
You can get it here :

>>>>> Download ti connect 1.5 for notefolio <<<<<

If you forget to install ticonnect, you will simply get this error 'TI Connect is either un-installed or missing. Please re-install TI Connect and try again'.
Like on this screenshot :
If you try to download it from the official TI website you should have something like this :
THIS IS BAD, DO NOT DOWNLOAD THIS TI CONNECT 4.0 !!!!
If you do that, you will have :
Download this ti connect 1.5 !

>>>>> Download ti connect 1.5 for notefolio <<<<<

Ok let's start ticonnect install :
Click Next.
Accept the ticonnect licence.
Keep the default ticonnectinstall directory.
Eveything seems OK so let's go !
Ti Connect installation is processing..
Ok at this point it seems OK :)
Now let's start installing notefolio.
You can download it here :

Ok next we need to have the notefolio editor on our calculator.
So find the file on your computer (in the folder : C:Program FilesTI EducationTI NoteFolio Creator).
Then send it to your calculator with ticonnect OR tilp. Here I will simulate it with the emulator tilem2 :
Ok send it (you can either click yes or no to garbage collect) :
The ti 83 plus fr will receive it slowly :
Press key apps to see notefolio entry :
Run notefolio :
Press enter.
Bad news : 'Upgrade OS to 1.15 or later'
I have to update the OS of this calculator :(
Update it and retry :
