I have the same issue, and it's not limited to iTunes. All of my software updates, including those for third-party apps have this issue. I will click 'update' it'll gray out and then, after a restart, it says it was updated, but it wasn't. Now, when click update (they are now both in the need to be updated and recently updated lists) it'll flash 'installing' for a second and then go back to having the update button and it will be added to 'recently updated' again. At one point I had an issue where I would click update and it would have a popup saying something about downloading and restarting after the update was finished, I would click download & update and then immediately the restart warning would pop up, and I would tell it to restart later. After doing this for an update, the notifications would stop and it would just flash the installing bar as mentioned previously. I clicked the 'not now' option on one of the pop-ups and now they don't show up and neither do the restart notifications and it goes straight to the installation bar flash, (which svcks because I wanted to try restarting using the notification for update installs instead of the standard way to see if there were any changes). I got 12.2 for iTunes by downloading off of the Apple website http://www.apple.com/itunes/download/ as per someone on another form recommended, and a few f the third party apps have their own unique update app that will probably work, but for the majority I have to use the App Store and I can't so I'm stuck.
