My emulator reports that it can't download the companion update. Nor can I use the internet on the emulator. How do I fix this please?

Make sure you don't have a firewall blocking connections to "dl.qyv.me" (which is where the companion update is coming from). We will be moving this later today to "download.appinventor.mit.edu").

None of those sites work. The first just says Foo Bar and is redirecting, the second just fails and says there is no DNS entry or something.

This actually is a nightmare for us. I have 33 computers, and a GCSE class (UK) doing an OCR controlled assessment based on app inventor (set by the exam board not us) - this has to be done in a set time, under controlled conditions for students to get their qualification. They were all working happily, and then last lesson, the Companion file needed updating. As there is no MSI, I had to manually remove then install this on all the machines.

Finally after a lot of work I got Version 2.11ai2 working. But that now hangs and want to try to update the companion file to 2.15. Nothing happens. The sites don't appear to be blocked but no update occurs. A message flashes up for a bit saying the site cant be accessed in a timely fashion.

As if you make your applications fail, when they are used in an educational setting. This is a MAJOR problem.

The new Companion is on http://dl.qyv.me/MITAI2Companion.apk Can you reach that address? (We'll be moving it to download.appinventor.mit.edu later today, but it doesn't exist as I type this).

Our firewall is definitely not blocking http://dl.qyv.me/MITAI2Companion.apk because I can type it into our browser and download the apk to the desktop. It's just that the emulator gives an error

Jeff, can you simply update the img in the emulator download package AppInventor_Setup_Installer_v_2_2.exe so at least we can get the newest version without having to rely on the in-app emulator autoupdate?

I have a class of 30 students dead in the water because we can't get the emulator to work anymore. (Is there an offline version of appinventor 2?)

I've attached the error screen:
