How can I tell if I have the 64-bit version of iTunes installed? As I understand it, the 64-bit version of iTunes is actually a 32-bit application, and so appears in the Program Files (x86) folder. Is there a way to see if the version of iTunes I've installed is the 32-bit version or the 64-bit version?
On OS X, you can open iTunes and go to iTunes -> About iTunes and it will tell you. On Windows, you can get to the same dialogue by going to ? -> Info, it won't tell you though. You can open the task manager and if there is a *32 behind the process name, it is 32 bit.

It looks like the Installer is 64 bit but the application remains 32 bit on Windows.
