So i have doors, and ti connect, i tranfer the filer to my Ti-84 Plus c silver edition, it works. i go into doors, and i open the app. It says i need to put the appvar in the archives. I have the .8xv appvar folder, but ti connect wont accept it to transfer! i cant play the games!, like 2048, flappy bird, cookie clicker.....

Okay, is Doors CSE Telling you this, or is the game/program you are running tells you this?

That is the games telling you that, not Doors CSE. Flappy Bird CSE, for example, requires an AppVar called FLAPSPRT to be put into your calculator's Archive. If you already sent that file to your calculator, go to [2nd][+] (Memory), choose 2: Men mgmt and delete, then AppVars. Scroll down to FLAPSPRT, and if it doesn't have an asterisk next to it, press [enter] to move it from RAM to Archive. The asterisk means it is Archived.

I have the same problem, but when I go to the look in the appvar file, there is nothing called flapsprt

Did you transfer the AppVar named FLAPSPRT to your calculator along with the program FLAPBIRD? If not, that would be the solution.

wow, that was stupid of me. Thanks!

No worries, it's an easy mistake to make. Let us know if you have any further issues or questions with Doors CSE 8 or programs that use it.
