I have been tinkering with Android App Inventor a little recently, and have it set up and running on my main laptop at home.

I often work nights and have a second laptop I sometimes take with me, and thought it would be good to get App Inventor up and running on it too, for those quiet late nights when I have nothing happening at work.

Since I’d already used this laptop to root my phone, I thought ‘No worries, all the drivers I need will be installed’.

How wrong was I!!  No matter how hard I tried, the blocks editor would not connect to the phone.

Ultimately, I had to remove everything that I’d previously installed HTC wise, and re-install just the App Inventor Extras Software. Once I’d done that and reconnected the phone, all was well.

I’d also had the Android SDK installed, which had it’s own copy of adb.exe to further confuse matters.

To be sure you’re using the right one, connect your phone, open a command prompt, and navigate to c:\Program Files\Android\appinventor-extras.

Type adb devices and you should see a list of devices attached. It’ll be something like

HT06SPL00260     device

If you don’t see that, then you’ll need to run through the the process here: App Inventor Setup.

It does work, just be sure to follow it exactly!!
