Can't Install aistarter

I downloaded the MIT aiStarter tool , its shows in my Files, but when I click for install, it aborts, the aiStarter is not working,
but when I try to open the MITAI2Companion.apk,,, it sends me to my Files, so I am going in circles and nothing is working nor updating.... HELP!

There are other emulators you can try.

What is your hardware, and what error message did you get?
