I just downloaded the update 5.4.5. It came as a torrent-file. The system has no program to work with that? What can i do now?
If you opt to download something via BitTorrent, use a BitTorrent client suitable for your operating system.
I didn’t opt this. There were no other possibilities. Now i downloaded a help-file, but it doesn’t open and i do not know how to open it.
No, you opted to. A torrent-based download is just one of the options.
Try asking a better question.
