Question: ITunes 11.7 installation problems

I just bought the new IPhone 8 Plus which requires the last version of ITunes 11.7.

I need sync with ITunes in my PC Sony Vaio using Windows 10 Home 64 bit.

I downloaded from ITunes (64x) correctly, but the installation process fails, I have tried several times with no success.

The message I got "The installation of Apple Application Support did not complete successfully"

Then I have to click the "Finish" button, and I Try again and again.

What is the problem? What I need to do ? Can you help me?

iPhone 8 Plus, Windows 10

I assume you really mean iTunes 12.7. In any case, see Note 1 in the Removing and reinstalling iTunes and other software components section of turingtest2's excellent troubleshooting guide at:

Troubleshooting issues with iTunes for Windows updates

or the Apple version at:

Remove and reinstall iTunes and related software components for Windows 7 and later - Apple Support

Correct is ITunes 12.7, my bad. So, I tried uninstall the programs sequenced as says in the link you posted, but I can not uninstall QTimes...my laptop send me next message: "The Windows Installer Service could not be accessed. This occur if you are running Windows in safe mode, or if the Windows Installer is not correctly installed".

How do I fix this ? Thanks

It is the button at the bottom left of the screen. When the menu pops open there should be a search box you can type into. Or you can use the Windows Logo Key + R to open a Run dialog box and type Notepad.exe into that, or you can find Notepad somewhere in Windows 10's launch screens.
