Installation

Prerequisites

Since App Inventor extensions are written in Java, you need to have the Java JDK version 8 or above installed on your system. To make sure you have the correct version of JDK installed, run java -version in your favorite terminal app. You should see an output similar to this:

$ java -version
java version "1.8.0_121"

Windows (64 bit)

• Create a new directory C:\Rush. (You can create the directory in any drive and name it whatever you want.)

• Unpack rush.zip into the newly created C:\Rush directory.

• In File Explorer right-click on the This PC icon, then click Properties -> Advanced System Settings -> Environmental Variables.
