i have no clue what that is or how to check if i do or dont have it
in that case you haven't installed one of them.
okay, let's try the following procedure.
Download and install the Windows Installer CleanUp utility. then use it to clear any existing QuickTime installation configuration information from your PC:
Description of the Windows Installer CleanUp Utility
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.
next, we'll try to 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?
