The issue is, because of the announcement, you are all trying to download at the same time, so both our two mirror servers (one in Europe, the other in the US), are being quite stressed, even if we don't keep the big installers on our site, just the Live Updates.
However, since the installer is brand new, it doesn't need to download anything, since today there's nothing newer online compared to what's included in the installer so, the easiest solution, if you don't want to wait while the network becomes less congested is:
- Install with the network disconnected
This will run the installer entirely offline but, as I've said, it has been updated right now, so there's nothing else or newer that it needs to download from the servers.
