Making sure you have the right Java version

1. Make sure you have Java installed. (how to install Java)
2. Open the terminal or command prompt and enter java -d64 -version.

It will output something like:

java version "1.8.0_202"
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)

This output could be different for you.

• Make sure your java version is 1.8.0 (Java 8), Java 9 and higher is not supported at this time.
• If it says This java instance does not support a 64-bit JVM, make sure you installed 64-bit Java (the online installer may not always install 64-bit Java, try the offline installer)

3. If you don't, install Java again using this tutorial. (you can install this alongside your existing Java installation and it shouldn't cause any problems)
