Launch4j - java-executable wrapper -- Windows7

Scenario: java-app wrapped with launch4j -- works fine on the dev-machine with Windows Vista -- on a plain Windows7 machine it asks to install Java JRE - but wont start the application.

Anybody managed to create an executable using a java-wrapper for Windows7.

Background: - jar has all dependend jars and resources 开发者_如何学JAVA- tried with a custom manifest as well as a build in manifest pointing to the Main class

Thanks for anykind of help

launch4j is not a JRE. It neither converts Java's object into a executable binary format to be run in Windows.

It explains it pretty well: http://launch4j.sourceforge.net/

I use NSIS instead of launch4j to launch my java apps:
