aiStarter update MIT AI2 Companion2 to 2.58au

Ok. Is it in C:/Program Files(x86)/AppInventor as shown in the image and do you see the files indicated?

Maybe. CCleaner is a utility used to clean potentially unwanted files and invalid Windows Registry entries from a computer. A tool like this could cause issues, depending on if it decided one of the aiStarter files is an issue. Sorry, I can't tell you it is problematic or not.

Yes, there are all there!

I dont see a commands-for-appinventor

Post a screen shot of what you DO see.

I had to reinstall it multiple times, but no success.

use some other emulator instead like memu play or noxplayer
