The iTunes Repair Tool for Vista 1.0 will repair permissions for important files required by iTunes to play your iTunes Store purchases. iTunes 7.0.2 may work with Windows Vista on many typical PCs. Apple recommends, however, that customers wait to upgrade Windows until after the next release of iTunes which will be available in the next few weeks. Customers who have upgraded to Windows Vista and are still experiencing issues playing iTunes Store purchases should download and run the iTunes Repair Tool for Vista after re-installing iTunes 7.0.2.
