I was finally able to do this. Here's how. First you need winRAR or 7zip to fully extract the installer (I tested this with iTunes Switchless 8.2.1.6 English.exe). Use winRAR/7zip to extract the installer package to another folder (I used C:\temp\iTunesInstaller). Next, drop to an admin command prompt and change to the directory you extracted the package to. If you type "DIR" in the command prompt, you should see this: Directory of C:\temp\iTunesInstall 2009-10-12 12:56 <DIR> . 2009-10-12 12:56 <DIR> .. 2009-10-12 13:12 4,826,112 itunes.msi 2009-10-12 12:56 <DIR> Redist 2009-10-12 12:56 <DIR> Program Files 2009-10-12 12:56 <DIR> Application Data Now execute the following line, substituting the iTunes folder and iPod folder to where you want them to be. itunes.msi INSTALLDIR="D:\Apps\iTunes" IPODINSTALLDIR="D:\Apps\iPod" /qb /norestart This doesn't work for me unless I also add the /qb and /norestart options! After installation, there's still a tiny bit of apple contamination in C:\Program Files\Common Files\Apple but it's only 20MB worth. -Bit. How were you able to extract itunes.msi from the switchless installer? 7zip didn't recognize it as an archive.
