Cant install QuickTimeInstaller.exe or iTunesSetup.exe and IE9 SmartScreen Filter reports the program is not commonly downloaded and is not signed by its author. I run it anyway, but "is not a valid Win32 application". Tried Firefox

I followed the Article TS1406 (recommended solution) on both a Windows 7 OS and an Apple OS, tried Safari and Firefox, tried using 'Upgrade ITunes' button on my old version of iTunes, then uninstalled ITunes, then QuickTime, now can't install either because I'm getting the same error message when I download and choose Run > 'not a valid Win32 application'. On IE9, the SmartScreen Filter returns a warning that the file could harm my computer because it is not commonly downloaded. I tried downloading it from other internet sources, but that's risky, and anyway, it's still causing the same errors. What else is there to try? If I can't find a solution, I can't use my new Iphone 5
