Java Virtual Machines

InstallAnywhere 2020 SP2

InstallAnywhere-generated installers are Java based. They require a Java virtual machine (JVM) to run.

You can bundle a JVM with your installer, thus eliminating the possibility that the installer will not find a suitable JVM for the product or for the installer. You also have the ability to configure how the installer searches for a JVM and customize the search that the installer does on behalf of the launchers it deploys.

Finally, you can use the Choose Java VM panel in the Pre-Install sequence of your installer to enable end users to choose from a set of JVMs to use for the products that they are installing.
