Q: I can't install the newest iTunes on my windows 10 pc.

The general troubleshooting advice when iTunes fails to install properly (and reinstalling or repairing it does not work) is to remove not only iTunes but all related components, reboot, remove the target installation folders and reinstall.  See turingtest2's excellent iTunes for Windows Troubleshooting page at:

Troubleshooting issues with iTunes for Windows updates

especially the section: Removing and reinstalling iTunes and other software components

It also has a section on downloading iTunes: iTunes installers

With that error message try repairing Apple Software Update from the programs and features control panel, then try installing iTunes again.

Hi. I have the same problem. I had read on a blog that I had to uninstall everything I had from apple and so I did. Tried again to install the new version and it didn´t work. So, what I did was to find an older donwload I had from 2014, install it and from then start over. Still, nothing. I can´t seem to find the software update you talk abou so, no way to repair it. I only have application support (32 and 64 bits) and the mobule support. Do you have any idea to solve this issue?

Appreciate your help, thanx.

If Apple Software Update is no longer listed, but there are remnants of it that prevent a normal installation, then see the section Install missing components and install all of the other parts of the current version of 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 performance issues or compatibility with third party software.

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

If you've tried the suggestions above without success then another option is to revert to the previous build of iTunes that worked for you. See the roll back advice at iTunes installers. Rolling back from 12.3.3 will involve restoring the pre-upgrade library from the Previous iTunes Libraries folder. Your library isn't going to work with a 2014 version of iTunes.
