Error message when trying to load iTunes

Question

Every time I've tried to load iTunes by clicking on the icon I get the error message "iTunes has encountered a problem and needs to close. We are sorry for the inconvenience."
Anything I can do about this or is it out of my hands?
btw, I updated my version before asking this question

Answer 1

Try to open quicktime player
If quicktime does not open, then quicktime needs to be reinstalled.
If quicktime does open, then some other program is blocking itunes.
The easiest way to reinstall quicktime is to:
1. try to remove quicktime from control panel > add/remove programs
1A. some times quicktime will not uninstall. That's ok
2. drag the c:\program files\quicktime folder to the desktop
3. open c:\windows\system32\
4. drag any thing that has the full word "quicktime" (not a qt or particial word) to the desktop. (This would be something like quicktimevr.)
5. close my computer
6. back in add/remove programs, find itunes
7. click on change/remove
8. when the wizard comes up choose repair itunes.
This process will reinstall the version of quicktime needed to your computer.
Now if quicktime player opens ok, here is an article from the appe support website that might help.
