Q: iTunes Failed Update

Hello,

Please cancel this failed install. Then re-run it, but before you do: right-click on the setup file and choose "run as administrator"

More information about that here: http://windows.microsoft.com/en-us/windows7/how-do-i-run-an-application-once-wit h-a-full-administrator-access-token

Hello again,

Too bad the easy fix didn't solve it.

You're next move is to do this: Remove and reinstall iTunes and related software components for Windows 7 and later - Apple Support

Please stick the 1 to 6 order as listed in the article

I also want to emphasize that removing all this software will not delete your iTunes library music, playlists, etc etc.

Try repairing Apple Software Update from the Programs and Features control panel, then reinstall iTunes.

For general advice see Troubleshooting issues with iTunes for Windows updates.

The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach.

Review the other boxes and the list of support documents further down the page in case one of them applies.

The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.

Your library and device backups should be unaffected by these steps but there are links to backup and recovery advice should it be needed.
