ITunes 7 won't start with Digidesign hardware

Question

Hi, I do not hope I am the only one out here, that are experiencing a major problem in the new iTunes 7.
IT SIMPLY WONT START!
I used to run iTunes 6.x.x over my Digidesign Audio hardware (M Box 2), with no problems at all. But after upgrading to version 7, the app fails to load. (Error 0x666d743f)
I'm pretty sure the problem is, that the new iTunes don't support Digidesign hardware. Because I also tested version 7 on a Digirack 002 audiocard and got the same error.
This must be an undiscorved error for Apple, because you are able to buy M Box 2 at the Apple Store. (Why would Apple sell a audiocard that is uncompatable with iTunes??)
I hope some of you knows some more about this problem, I suppose we are a lot of people who would like some kind of solution.

So I try to uninstall Quciktime, but guess what? The uninstaller refuses to work and it won't appear in the "Add/remove" programs control panel applet.
let's try this first.
Download and install the Windows Installer CleanUp utility. then use it to clear any existing QuickTime installation configuration information from your PC:

Next, we’ll manually remove leftover program files and folders.
1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
2. In My Computer, open Local Disk.
3. Open Program Files.
4. Right-click on the QuickTime folder and click Delete from the shortcut menu.
5. Navigate to C:\Windows\system32\.
6. Remove the files QuickTime.qts and QuicktimeVR.qtx.
7. Restart your computer.
after the PC has restarted, we'll try to get a fresh copy of QuickTime into that PC by doing a repair install of itunes.
in Add/Remove, select iTunes. click "Change", and then click "Repair".
if the repair install goes through okay, does iTunes launch properly again?
