A few weeks ago a group of 3 PC's running W7 x64 downloaded SP1.
All 3 failed at the same point and were rendered unbootable. In the end I had to manually copy the backup registry files to get them up and running again.
However, now all 3 are unable to install any MSI files.
I have done every fix I could find on the internet and still no go!
Really really want to avoid reinstalling from scratch.
From memory these were originally W7 HP machines, upgraded via the Upgrade disk. I tried doing an inplace upgrade using that but the error is the current version is newer.
Currently downloading the SP1 readiness tool, with a view of reinstalling SP1...but considering it failed last time I'm hesitant to say the least.
I have closed the links now to the pages I had fixes for, but it was a guy who had the same problem and had listed loads of suggestions. He fixed via in place upgrade...I cant it seems.
