Here are the links to the latest versions, as of today: Just make sure to install them in the right order (and to install the Android SDK/NDK after installing Xamarin.Android) I haven't tested whether installing them separately will work or not, but it probably will. There's a way to find the direct URL for each installer by checking the XML used by the Platform Installer (located at \AppData\Local\Temp\Xamarin\downloads\InstallationManifest.xml). Similar searches on the Xamarin Forums yielded no results as well.

I did so, but all that's available there are older versions of Xamarin Studio and the universal installer. According to the official docs (whose pictures are outdated, by the way) you should login to your account and then head to the download page where you could find links to different versions of Xamarin.
