I woudl suggest trying to unistall iTunes and Quicktime, then reinstall them. make sure that nothing is running in the background. I found an itunes.exe for 32bit running and I am not sure why. i am unistallign iTunes and Quicktime and will reintall. I was also told to make sure nothing is running that uses Quicktime. Will post an update if things change.
Let's check if this file APSDaemon.exe is the problem here.
Close your iTunes.
Press Ctrl-Alt-Del key and choose Task Manager. In the "Processes" Tab, select the file APSDaemon.exe and click End Prosses button, then close the task manager window.
Now open itunes and see if it is working?
If that works, to prevent having to do the same process everytime you restart Windows, go to. START button, type in
Click STARTUP Tab, Uncheck "Apple Push", click OK.
