A few things to add.
I said on my original post the following:
I then went to my MyMusic\iTunes folder.
DO NOT DELETE the iTunes Media or the Previous iTunes Libraries
folder.
I did delete all of the other things in the iTunes folder.
Again do not delete the iTunes Media folder or you will loose
all of your music, podcasts, books, apps etc...
Remember that your present itunes library files are in this folder. I backed mine up into a separate folder, in a different folder on my hard drive before
deleting what was in the itunes folder. If you intend to keep your current library (given that it was working for you and was not corrupted, then don't delete it. I wanted to be sure in my case that the complete reinstall would work
so I took a no prisoners approach.
If you have an external backup drive it would be a good idea to back up your entire iTunesfolder before uninstalling
all of the Apple programs.
Also when all of this trouble started for me with this itunes update I accepted an update from Apple which consisted of iTunes with Quicktime AND Safari. Safari had not been on my PC before. I am guessing that this combination of programs being installed caused the failure of a clean working update.
I notice that Apple latter dropped Safari from the update package.
So far all isworking well with the newest iTunes on my PC. I connect to the iTunesstore every time.
After restarting the computer again I can now just click on the iTunes shortcut without selecting Run as Administrator
to start it. I was able to sync my iPad to iTunes. Had to clear up a huge scattering of my App icons every which place
across pages of the iPad though.
All together not a pleasant experience and a huge killer of weekend time.
