I have tried turning off ESET, the security software. From the emulator phone I get a message that there has been a 'parse error in the package.' and nothing further happens. At the same time, AI2 announces that an update needs to be installed. 2.11ai2, which then announces that it has stopped working and gives the option to either Force Close or Wait. Initially, the emulator starts, and eventually opens Companion v. I have not been able to get AI2 connect with the emulator from either Firefox or Chrome. Literally, yesterday, Sunday May 11, I downloaded and installed the App Inventor Emulator on 16 computers in my lab.
