Google Cloud Connect offline installer

I always face problems installing plugins from Google. it seems their installers download is blocked if we are behind a firewall or because Google uses a proxy that blocks unauthenticated content ; or maybe for other internet connectivity reasons.
I recently failed to install the Google Cloud Connect for MS office plugin . The download fails without reporting any Error number.
A workaround is to directly download the plugin installer from the below link :
