iTunes will not load or install

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. When reinstalling temporarily disable any anti-virus software and right-click on the downloaded setup file and use run as administrator.

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 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.

Have you tried the "for older video cards" release?

Have you tried reinstalling the last version that worked for you?

When do you get that error? Have you tried using the Microsoft Program Install and Uninstall utility with the install phase?

I have the same exact problem and can't fix the issue, so I basically no longer have iTunes.

It's very frustrating, especially with Apple having a seemingly undeserved reputation as being easy to use.

:-(

Hey I had this exact same problem after the windows update. Just to be sure, did you uninstall absolutely everything that is listed under Apple in the Control Panel? (Bonjour, application support, Software update, etc) I couldn't get iTunes to run and had iTunesadmin.dll fail to register until I uninstalled all. Then I tried again and it went through.

i have the same problem, i tried to reinstall all components of apple but doesnt work.

clean reg, check for fix errors, try to install for old video cards but nothing.

I tried deletign and re-installing components, but, I've reached my limit. I'm not a computer professional or computer programmer, so there's only so much I can do. It's really frustrating how unhelpful Apple is.

I'm left with no iTunes and searching for another service provider from whom to purchase music, videos and movies.

Other ideas perhaps not explicitly mentioned so far in this thread are to disable any anti-virus software and run the installer as the administrator. You could also try rebooting into a new user profile that you have given administrator privileges to and see if that user can complete the installation without receiving the "failed to register" warning.

See the section Install missing components. Which component fails to install, and are there any error messages?

tt2

Is this during a component wise installation or using the main installer?

Did you disable any antivirus software?

Are you an administrator or are you running the installer as the administrator?

What level of User Access Control is in force?

I have disabled firewall, run as administrator, tried older versions. Still no success. PLEASE HELP

See the section Install missing components. Work with the current installer. Which component fails to install, and are there any error messages?
