Windows 7 64-bit Itunes crashes when I go to itunes store

Question

Every thing seems to work fine except that when I try to access iTunes store it crashes, or update my apps.
I have updated my path C:\Program Files (x86)\Common Files\Apple\Apple Application Support and no change.

Answer 1

I had exactly the same issue today with my Windows 8 PC, and I tried the suggestion below provided by another person in this forum - and it works.
Try adding C:\Program Files (x86)\Common Files\Apple\Apple Application Support; to the system variables PATH
iTunes tries to use QTMovieWin.dll and that the file is in the directory
Guide to add a PATH:

Drag the Mouse pointer to the Right bottom corner of the screen
Click on the Search icon and type: Control Panel
Click on -> Control Panel -> System -> Advanced
Click on Environment Variables, under System Variables, find PATH, and click on it.
In the Edit windows, modify PATH by adding the location of the class to the value for PATH. If you do not have the item PATH, you may select to add a new variable and add PATH as the name and the location of the class as the value.
Close the window.
