To download Google Cloud Connect to sync your documents with google docs, you need to download the installer from http://tools.google.com/dlpage/cloudconnect, but this won’t work in case you are behind a proxy which blocks unauthenticated content. In that case you can directly download the MSI installer from http://dl.google.com/dl/appsconnect/googleconnectinstallerenterprise.msi
For more information on Google Cloud Connect you can go to http://tools.google.com/dlpage/cloudconnect
