exe4j is trialware. Its use is not time limited, but restricted to evaluation purposes. Evaluation warnings are removed after purchasing an exe4j license.

exe4j requires an installed JDK/JRE >= 1.5. This is only a requirement for the exe4j wizard, not for the JREs that can be used by the generated launchers.
