Downloading setup / installs
Not sure if this is the correct place to log this but here goes. Your "alternate" download methods for the setup are seriously suspect. The torrent never completes and vacillates between 84% complete and then complete over and over and never finishes. Your download from a "trusted third party provider" sets off alarm bells with my anti-virus and gets quarantined.
I eventually had to use the download link in the small print to do a direct download.
You might want to check out if your "trusted" third party has been hacked or something.
