title: Xcode 4.1 fails to install on my Snow Leopard Mac OS X 10.6.3
body: <p>I recently downloaded Xcode 4.1 to install on Snow Leopard Mac OS X 10.6.3, however it fails to install. When I clicked to install the package, it gives me a "com.apple.installer.pagecontroller error-1" and says it fails to install. Does anyone know why this might be the problem? Thanks in advance!! (I have paid the $99 and joined Apple development).</p>
