Also, just because those applications use a Windows installer to get themselves loaded onto Windows machines, it doesn't follow that the result of the installation is a Windows exe file. If you want to get your application installed on other people's Windows machines, I definitely recommend using a Windows installer to do that. But I don't recommend using those applications that convert your application into a standalone exe file. They usually aren't necessary and often people seize upon them because they don't realize that they can use a standard Windows installer instead.
