itunes won't launch after upgrading to 10.10.3. I have restarted twice and it still isn't launching. I tried to delete it to re-download it, but Mac doesn't let you delete it. Any ideas?
MacBook, OS X Yosemite (10.10.3)
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears.

Select the Recovery HD and click on the downward pointing arrow button.

Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Apr. 2015 Niel post: Re-install iTunes application - https://discussions.apple.com/thread/6990002?answerId=28055467022#28055467022 - delete the old application first. A similar technique by Ben.d using Terminal to delete the application - https://discussions.apple.com/thread/6985231?answerId=28036630022#28036630022 Normally you don't have to delete an old application but this time it seems to be necessary for some.
Ben.d's delete itunes and reinstall it worked. Thanks
Having similar issue.
Wish Apple would fix this instead of having to use a work around 😠
