Accessibility Assistant (AA) requires Java 10 as a minimum.
Recently Oracle changed their Java license model to be a bit more aggressive than previously. You can read more about it here:
This complicates things a bit for AA. However, to accomplish what we do with AA we have no choice but to utilise a minimum of Java 10 and upwards.
The good news is that we also support OpenJDK (https://openjdk.java.net/) which is the open-source version of Java.
Getting Java to work
After installing Java you need to verify that you are in fact running version 10 as a minimum. This can be done by opening a command prompt and typing java -version. If it states version 1.8 then it is not sufficient.
If you are using OpenJDK make sure that the path parameter to Java in system variables contains the full path to where you placed your OpenJDK library.
