ITunes 7.6 (or QuickTime stand alone) won't run on XP

Question

Dear friends in iTunes Land. I thought Mac SW was supposed to be user friendly but this is the worst install I've ever faught on an XP machine. Would appreciate any insight.
... I've done all the clean uninstall/install... Install Quicktime stand alone. All of the suggested items on the list (first few pages) and still I get a Windows 'Send Error Report' popup when I launch either QT or iTunes. This is the Error Signature when I try to start Quicktime:
EventType : BEX P1 : QuickTimePlayer.exe P2 : 7.50.61.0
P3 : 4837c166 P4 : QuickTimePlayer.exe P5 : 7.50.61.0 P6 : 4837c166
P7 : 0000130d P8 : c0000409 P9 : 00000000
I don't know what to try next... except sell my new iPod on eBay.
Thanks in advance,
Jason

The QuickTime problem will probably be causing the iTunes problem. (iTunes needs a properly functioning QuickTime in order to work correctly.)
So let's try swapping out your existing QuickTime again, taking a few additional explicit precautions.
Head into your Add/Remove programs. uninstall QuickTime.
Next, we’ll manually remove any 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. (If “Hide filename extensions for known file types” is enabled on the PC, then those two files will appear as “QuickTime” and QuickTimeVR”.)
7. Restart your computer.
Next, we'll get a fresh copy of QuickTime into your PC by doing a repair install of itunes.
Switch off antivirus and antispyware applications prior to the repair install.
Go into Add/Remove and select itunes. Click "Change" and then click "Repair".
If the repair install goes through okay, restart the PC and try launching itunes again. Does it launch properly now?
