iTunes 12.3 installation error on Windows 10

Press WinLogoKey+R, type Regedit in the Run dialog and press Enter/Return.

Click Edit > Find, type in itunes6464.msi (or the name of the problem .msi if different), change the Look at boxes so that only Data is ticked, then click Find Next.

You should find it somewhere like:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\{Long string of letters & numbers}\SourceList

Right-click on the immediate parent key with the long string of letters & numbers that contains the SourceList with the reference to the .msi file and click Export, save it to say the Desktop with the name iTunes.reg so the data can be restored if removing it doesn't help. Now right click on the key again and select Delete from the context menu. This should stop the Windows Installer from looking for the .msi when you reinstall iTunes.

If the install still won't go through then double click the iTunes.reg file you made to restore the data to the registry, then use the method shown at Install missing components to unpack the installer of your previous iTunes installation and extract the .msi file you require. Double-click this to uninstall the component. There are links to recent builds of iTunes in the Older versions section of the user tip Troubleshooting issues with iTunes for Windows updates.

Try this

1. open Control Panel > Uninstall Programs

2. Right click on Apple Software Update > Repair

3. Try Install iTunes 12.3

*If it didn't work Remove and reinstall all apple software

No worries, I suspected an incomplete reporting of the error and assumed it was a missing .msi message. As you've found the good news is that you don't need Apple Software Update for iTunes to work. You can try installing ASU from one of the other current installers, grab it from a previous one, or wait until the next release. I'm in the middle of installing the "for older video cards" version so I've yet to see if I get the same issue with it.

ASU installed fine for me. 😕

Thanks, this worked for me.

I know you have found your solution already. But for anyone who has come across the same error, this is what i did to resolve it. go to Windows, 'Uninstall or change a program' Select ASU, then repair it. once this is done install the latest version (or any other version you had the issue with) of iTunes. It should be installed without any issues..

Cheers

Thank you turningtest2 this solution worked for me on windows 7 sp2.

You're welcome. 🙂

Thanks this worked a treat for me - repair ASU then install.

Can anyone offer some sort of help for the "itunes was not installed correctly. Please reinstall itunes" error 7 (windows error 193). I have tried everything on nearly all the forms, i even contacted apple support. which was very unhelpful. Im currently running windows 10 .Any help would be appreciated

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.

If the issue persists and you have a 64-bit system try the for older video cards version which is a 64-bit installer for mostly 32-bit code, similar to all 64-bit versions of iTunes up to 12.1.

If you've tried the above without success then see the method in Install missing components. What component fails to install, and what error message does it give? See this post for steps to produce detailed logs of the installation which may reveal why iTunes won't install.

This fixed it in my situation. Thanks!
