I've tried downloads for a few days now, and I have the same problem each time.
at the final installation, there is only a few seconds of loading, and it reports the installation has failed.
I have tried this in safe mode, and also adjusted the msconfig none of which have helped.
The first one is to find that is the problem installation files or your machine? Can you try to use your downloaded files to install at another machine, see if it works?
