I'm interested in cross-platform capabilities of the above tool. Has anyone used it? Does it allow creating installers for different platforms directly under Windows, or I have to install Mac and Linux versions separately in order to build installers for those systems?
Thanks in advance :)
Answer from their customer support:
Yes, with the Multi-Platform Edition you can create installers for Windows, Mac OS X and Unix on any platform.
Looks good so far.
Another commercial alternative, if for whatever reason install4j does not work for you is link text (disclaimer, I am the author). It is also capable of producing installation packages for Windows, OS X and Linux
