Installing the Java Runtime Environment

QIE is a Java application which runs inside a Java Runtime Environment (JRE). QIE requires a 64-bit JRE, version 17 or newer. See Supported Java Versions for the distributions QIE supports and why 64-bit matters.

For Windows based installations, the Amazon Corretto JRE is freely available and can be downloaded from https://www.qvera.com/getjava/windows. The QIE installer offers to do this for you, so on Windows there is usually nothing to install separately.

For Mac based installations, the JDK can be installed via terminal with the command brew install openjdk@17.

Linux based installations typically use the OpenJDK, although any Java environment can be manually downloaded and installed. QIE is supported in Linux environments using OpenJDK, Amazon Corretto, or Oracle's Java environment.

Note

Where a server already has more than one Java installed, installing another one is not enough. QIE uses the JRE configured for its service, not whatever java resolves to on your shell path. See Pointing QIE at a specific JRE.
