After downgrading to v10.7 iTunes keeps reverting to v11.1
I recently allowed iTunes to upgrade to the latest version and like many other people, disliked the new look so much that I decided to uninstall it and try to go back to version 10.7. I found the information I needed to do this on this community ( thanks turingtest!).
I was very relieved to be able to get 10.7 back and running smoothly and everything seemed to be in place as before except that some tracks were marked with ! iTunes did not know the location of these tracks but I was able to correct all of them. My previous version before the update was an earlier version than 10.7 and I was very pleased to see the new feature allowing me to re download some purchases which had gone missing during a transfer to a new computer two years ago.
Upon rebooting the next day iTunes had reverted to version 11.1 I uninstalled it, rebooted, installed 10.7, replaced the iTunes Library.itl file with a saved version from the first 10.7 installation and the program opened, running 10.7 perfectly with the changes I had made the day before intact.
Since then I have had to repeat this uninstalling an reinstalling half a dozen times. 10.7 just will not stay in place. The length of time it stays varies from a couple of days to an hour or two. Rebooting does not seem to always trigger the change and using sleep rather than shut down does not seem to keep 10.7 in place. The reversion to 11.1 seems to happen instantly and it even happens while the computer is running, once it even happened while iTunes 10.7 was running but minimised. I have never seen any software behave like this before!
I have tried uninstalling everything Apple related - iTunes updater, Apple App Support, Mobile Me and Bonjour but to no avail. They are all reinstalled with 10.7 anyway but just uninstalling iTunes Updater did not help, nor did checking 'Do not check for updates' in Preferences. I recently disabled System Restore also. This morning 10.7 opened and then with in five minutes I was back to 11.1
