I see, didnt noticed that eariler. Installers could detect if any JRE is available, then download/install them if needed. (commerial installers like http://www.advancedinstaller.com/ or http://www.denova.com/ does that), if not make a notice to download it from sun's page.
As for whether installer can uninstall other applications, its yes (esp if you have admin privillages in windows). An example is Google pack - http://pack.google.com A batch file can be very written quickly eg.. :: LilypondPackageInstaller.bat start /wait "ftp://blabla.org/java5.exe"; start /wait "http://blabla.org/lilypond.exe"; start /wait "http://blabla.org/jedit.exe"; start /wait "http://blabla.org/lilytool.exe"; But can the user might be confused after installers after another installer popups is a question. Maybe setting up a webpage like "Ultimate guide to lilypond on windows" with links to all the installers can be as easy but I thought the flash tutorials http://web.interware.hu/fodber/lilytut/ was quite good already.
