Determine whether JRE is installed using Install4j

I have created an installer for my Java app using Install4j.

I want to check whether JRE/JDK is installed on my system or not. This checking will be performed at the start-up of the installer. So how can i do that ?

And help will be highly appreciated.

install4j always checks whether a suitable JRE is available, otherwise it cannot run. If no suitable JRE is available, an error message will be displayed.

If you do not want to statically bundle a JRE into the installer, you can use the "dynamic bundle" option that will download the JRE on demand. This is configured on the "Bundled JRE" step of the media wizard.
