That problem will be causing the iTunes problem.
So let's try swapping out your existing QuickTime for a fresh copy.
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?
(If, however, you get an error message on any of the install or uninstalls, let us know what that message says. Precise text, please. Include any error message numbers if you're getting any.)
