    1. Thanks.
      A great collection of all the possible ways to get round it, that I’ve found anywhere else.
      Net/Microsoft answers wisdom says I wait 4-7 hours each time, just to check it’s actually stuck. Four methods using the upgrade assistant, 28 hours, minimum. NO problem, have nothing else to do 🙂
      I just wish it was smart enough to know it had already downloaded the files 3 times & didn’t start from the beginning again & again.
      On the answers site there’s a very nice comment echoing a frequent thought of mine; there could be a parallel universe where users are just users & these things just work, before they are shipped.
