if you are running windows 7 and facing this app crash , the only solution that may work is windows update, the computer i have seen was running windows 7 without service pack 1. i just ran windows update & installed service pack 1. after restart iTunes opened without any problem.

    • If your windows is genuine you should get service pack update through windows updates, just check for updates and it will give you list of available updates.
      If you want to install manually, 1st check your version of Windows 64 bit or 32bit. 32 is called x86, then search for matching service pack,
      In my case i installed it through Windows updates in control panel
