1. Remove iTunes and related components from the Control Panel (http://support.apple.com/en-in/ht1923)
Use the Control Panel to uninstall iTunes and related software components in the following order and then restart your computer:
3. Apple Software Update
4. Apple Mobile Device Support
6. Apple Application Support (iTunes 9 or later)
Important: Uninstalling these components in a different order, or only uninstalling some of these components may have unintended affects.
I recently broke down and decided to upgrade to the latest version of iTunes. Low and behold, I am now getting a error message when I launch iTunes:
iTunes.exe - Entry Point Not Found
then after closing this out I get the 7 (127) iTunes was not installed correctly error.
With the help of Apple, I've tried everything from uninstalling and reinstalling iTunes and all of the accompanying programs (in the proper order and running as an admin) to trying the .Net repair (but I get a message telling me I have an equal or higher version already installed and I cannot attempt a repair.
Apple has been very gracious and has elevated it to supervisor and engineer level. They have told me when I have time to call them back we will somehow figure out a solution, but I've gotten the impression mine might be a rare case. Has anyone experienced something similar and stumbled onto a solution? I am running Win 7, but it's a 32-bit version, so we're wondering if that has something to do with what's going on. Thanks for any help.
