iInstall Reborn is a great tool, and the command line option is a great addition. Your suggestion of using Launch4j to convert the executable jar into an exe file worked great too.
One feature of the old iInstall that we have not been able to find within iInstall Reborn is an option to specify a “command to run after installation”. This was a really useful feature, as it allowed us to automatically run an update program on the customer server once libraries and objects were deployed. Is this feature something that you would consider adding to iInstall Reborn?
