Since a problem with iTunes, new installations are not being fully recognized. iTunes does a quick configuration when I click the icon before coming up. Then it will not store authorization on this computer and allow me to transfer iPad apps. I have tried fully removing all iTunes apps and reinstalling to no avail. This install problem also has happened to subsequent installations of other new applications. They try to reinstall or recoonfigure each time I boot up. Unfortunately, I do not have helpful restore points, Microsoft Fix-It did not solve it and various registry fix programs have failed.
