Installed the AppInventorSetupInstallerv22 (1).exe that I downloaded, accepting all the installer's defaults. The installation directory was chosen by the installer in C:Program Files (x86)AppInventor; Logged out and after logging in again - aiStarter is running; Killed all the BlueStack processes; Tried Connect/Emulator. As you know the App Inventor 2 emulator, works, but takes way too long to load and screen switching is very slow. It also crashes often, and has limited screen size.
I tried everything in the document. I got it to work once. I'm not really sure how. I think at the first 'Force Close' dialog, I clicked 'Wait' and then when the dialog came up in AI2 to upgrade Companion in the emulator, I selected 'Not Now' or whatever the button was. Eventually, the emulator connected with AI2. Trying to upgrade the Companion in the emulator otherwise just resulted in the Parse Error and the connection failed. After that, for some reason, it required a restart of the computer. Sometimes that actually meant a 'hard restart' using the button on the computer box. Not sure what happens there. Might be a memory issue not trapped by XP.
One of the technical staff will review your responses, so check back here frequently. They are very busy but do want to help. Thanks for the images.

My suggestion is that you do a complete uninstall of app inventor 2. Then, try once again, documenting everything that happens. Capture screen images where you get error messages etc. All this will help the technical staff to diagnose your issue.
This is an annotated part of the install process:
PART 1: App Inventor Setup Tools installed, updated and aiStarter is running.
This page will perform some tests and indicate whether you have the aiStarter program running and if you have the current version of the setup tools installed. From the AI2 browser menu, select Help>About to find the current version of AI2 and the date of its most recent modification. The About box also tells you which version of AICompanion you should be using with this version of AI2. Check and you know you have the correct AI2-Companion combinatio Did this step work?
If aiStarter is not running, then start aiStarter by locating the aiStarter icon on the desktop. When aiStarter was installed, the installer provided a desktop icon. There should also be a link in the start menu, or in the AppInventor directory located in the “Program Files” or “Program Files (x86)” directory. Now try the test page again. If the aiStarter is running then proceed to Step 4.
If aiStarter is still not running then you need to install the setup tools by following the instructions at the link below and try the test page again.
Don’t neglect the part of the instructions dealing with logging out (or rebooting) and running the uninstaller. Again, you must reboot your PC before runing the uninstaller from the Program Files directory, and then attempting to install/re-install aiStarter. THIS is VERY important.. yes, you need to log out / rebooting.
If aiStarter is running but your setup tools are not up to date as indicated on the test page, reinstall the setup tools by following the instructructions below and come back and try the test page again.

Repeat these steps until aiStarter is running and you have the updated setup tools.
Note: When the setup tools are installed aiStarter will automatically start when you log in to your Google account the next time.
For either of these issues, you will need to work with your network provider or your IT service to resolve them.
PART 2: Getting the emulator running on the computer
![]()
Once you are sure that aiStarter is running and your setup software is current, you can try starting the emulator. With App Inventor running in your browser, choose the “Emulator” option from the “Connect” menu, and the emulator should start. How fast your emulator starts is a function of your PC's cpu and the amount of memory available to the PC. On a Win 7 PC with lots of memory, the emulater may take only a few seconds to start; on slower PCs, the process might take a several minutes.The might take a few minutes.
The Emulator is a virtual phone. Starting the emulator will both start this virtual phone and will then run the MIT AI2 Companion in this virtual phone. There are several places in the process of starting the emulator where things can go wrong. Here are some hints to help figure out what the problem might be be.
When the virtual phone starts, you should get to a “home” screen that looks like this:
If you don’t see this “home page” then there is something wrong with how your computer is starting the emulator. At this point you will likely need to find someone who has access to an Administrator’s account on the computer you are using.
Be aware, you do NOT have the current version of Companion..it is imperitive that you have version 1.17 of Companion.. can you confirm that you have Companion 1.17?

They should log in and try to use App Inventor to start the emulator. If they can use the emulator with their administrator, but the ordinary user account on your computer your account cannot, then there is probably some restriction in place on your computer that is preventing App Inventor’s emulator from operating properly. You will have to experiment with removing restrictive settings and or disabling programs that enforce restrictions to see which one is causing the problem. Once this is determined you (or your administrator) should leave this program disabled or figure out how to configure it so that it does not interfere with App Inventor. We cannot tell you here exactly what you need to do because there are a lot of programs that are used to restrict and protect Windows accounts, and what you need to do will be determined by which program you are using. Some issues people have encountered include restrictions on access to the Web, prohibitions against running .exe or .bat files, and inability to access the commands-for-appinventor directory. One way to look for hints as to what might be wrong is to open a command window in the commands-for-appinventor folder, where the setup software was installed. Then try to launch the emulator manually using the command run-emulator.bat and see if there are any error messages.
Another possibility (on older computers) is that the computer is not powerful enough to run the emulator. Symptoms might be that the emulator starts, but never gets past a black screen.
PART 3: Getting the emulator to connect to App Inventor

Do you see the above screen?
If you see the virtual phone’s home screen (above) but cannot get any further, then there may be a problem with how the virtual phone is set up. You can reset the emulator by selecting the Hard Reset choice in the Connect menu. This will reset the virtual phone to the “factory” state it was in when the setup tools were first installed. Note: When you select Connect->Hard Reset you will see a dialog box warning you that it will reset the emulator. If the factory version of the MIT AI2 Companion is out of date, the system will lead you through the process for auto-updating the Companion, once the emulator is running.
If you cannot get things working at this point. You can try uninstalling and re-installing the setup tools. Did you do this uninstall? Nfs most wanted for mac direct download.
If this still doesn’t work, then you will need to find a system administrator (who can login to an Admin account on your computer) and try the steps listed in Part 2 regarding programs that might be interfering with App Inventor. Again, there are many such programs and we cannot tell you how to change their settings. You will likely need some expert help.
PART 4: Getting the emulator to update THIS could be your issue. Did you try this?
The emulator connects to App Inventor using an app (the AI2 Companion) that runs in the emulator. If this app is out of date, App Inventor will offer to update it. If the update fails, you can bypass the update temporarily, but you should update soon, since newer App Inventor features might not run on the emulator, and new apps might crash.
PART 5: Talking to the Emulator
Some people have reported getting the Emulator running and even the Companion, but then their blocks do not load. Instead you continue to see the “white screen” of the Companion claiming that it is waiting to get blocks.
The Companion listens on port 8001. If something is blocking that port, then it will not be able to receive any blocks. Similarly if another program is using port 8001 the same thing can happen.
To test if this is the problem, while in this state, use your browser to go to http://127.0.0.1:8001/
If you get a directory listing (it will start with “Directory /”) then you are talking to the Companion. Note: There may only be the line “Directory /” or you may *also* see a listing of files which you should recognize as project assets (images, sounds etc.). What you see isn’t important, it is the fact that you can see it.
If you cannot connect to http://127.0.0.1:8001/ then you will have to look at what other programs on your PC may be interfering with connecting to the Companion. This can be anything from a firewall, to another program using the same port.
The guy(s) who will help you will need to know the answers to the above questions. Yeah, I know you mentioned some of this, however, in places you seem unsure of what actually happened. We would appreciate you confirming the individual steps.
We will work with you to get you running.

Still using XP.recommend you have a GOOD virus checker as MIcrosoft stopped supporting Xp..probably not your issue.
