That's an unusual variation on the error messages for this sort of thing.
Here's what I think is going on. You've got a damaged iTunes program folder ... it's one of the Chinese language resource files (not sure if it's one of the simplified or traditional Chinese ones). Your iTunes uses "advertised shortcuts" on the desktop and in the start menu. The first thing they do before launching iTunes is check against the installation database to make sure that all the program files and registry entries that ought to be in place are there. The damage to the folder makes that check think the folder is missing, so it's doing a repair install of iTunes in order to try to replace the file. (That's the "Configuring iTunes" you're seeing.) Unfortunately, the repair install is finding what it thinks is a damaged
file instead of a missing folder when it tries to do the repair, and is getting horribly confused. So you're getting an error message. iTunes launches when you plug an iPod in because iTunesHelper (the thing that finds an iPod and wakes up iTunes when iTunes isn't running) doesn't do a check against the installation database for iTunes when it launches iTunes. Since I guess that you aren't using Chinese as an iTunes display language, iTunes is able to launch for you.
... long explanation, but what we're going to try doing to fix it (first of all) is pretty simple.
First, restart the PC.
Now open My Computer.
Open the C: Drive.
Open the Program files folder.
Open the iTunes folder.
Open the iTunes.Resources folder.
Open the zh_CN.lproj folder.
Drag the
DevicePrefsCalendars.nib folder out onto the desktop. If Windows won't let you drag it out, try renaming it
DevicePrefsCalendars.OLD instead.
After you've dragged out or renamed the folder, try launching iTunes. Does the repair install go through properly now without the error message? (If the iTunes Setup Assistant runs, *don't add files to your library when prompted,* or you'll end up with duplicates in your library.)
After the repair install/setup completes, does your iTunes launch properly?
