For the Java edition it would be nice to allow for post-install hooks so a run-once-only set-up wizard in Java could be kicked off automatically. Also, has anyone used JNI extensions with your Java native wrapper? I'm considering bundling JNIWrapper (
http://www.jniwrapper.com/index.jsp) with my product. It lets you do things like COM integration, Java system tray icons, Win32 calls, Java registry access, etc. from Java code. And here's the real kicker: what if the post-install hook itself required that native library in the PATH? Would the installer be able to load the DLL?
