Yes, still having difficulty.  The 'installing' screen is there all night long, but last night it said it had reached 49%, but would not go any further!  After turning the machine off again it was back to the starting to install screen again, 0%.  Since using your program, though, the machine itself, when I can get it to start, is working beautifully, apart from the installing and updating bit.  Wish I could get it sorted as it is competing with my blood pressure pills!!
