Jpackage from 32bit JDK (if somebody would build 32bit OpenJDK) would bake in 32bit Java runtime in app image regardless Windows is 64bit or 32bit. So the arch of installer is determined by arch of Java runtime baked in the app image. For simplicity we can assume that arch of Java runtime is the same as the arch of jpackage (this might not be the case for external Java runtime case though, but let's leave this possibility aside as it is not supported anyways). If so, checking of `sun.arch.data.model` system property would be better alternative to `os.arch`.

Sorry, I left this comment earlier, but it was lost.
