Java installation problem

Here's the issue: A while ago i tried installing the newest java jre update, but the installer wouldn't start (it downloaded the installer, i hit install, and nothing), i also tried the full installer, but that wouldn't start at all. (windows says it didn't install correctly… go figure) I then tried removing all older java versions, etc. with these programs: JavaRa Windows Installer Cleanup Utility I have tried several java installers, every single one failed: "chromeinstall-6u23.exe" "jre-6u23-windows-i586-iftw.exe" "jre-6u23-windows-i586-s.exe" Again, none worked, and still don't. They just close without any error message, sometimes windows pops up saying "'This program may not have installed correctly"
