can't download new 1.17 edition despite multiple attempts, reinstalling new drivers etc

have no required updates on my computer, have followed all inx, and spent over 5 hours trying to get this to work. utterly flummoxed. my system is windows 10 // intel //  64 bit

i know next to nothing about computers and feeling totally thwarted by this and the hours spent trying to get to this to work - previous edition was fantastic
