Hi Michael-Keller,

Thank you for participating in the Apple Support Communities. We understand you're having trouble downloading and installing iTunes on your PC. You'll want to make sure you're following these steps: Download and use iTunes for Windows 10 - Apple Support.

" Download iTunes for Windows 10 from the Microsoft Store

If you can't access the Microsoft Store

• Download iTunes 12.10.11 for Windows 10 (64-bit)
• Download iTunes 12.10.11 for Windows 10 (32-bit)

Manually manage and sync your iPhone, iPad, or iPod touch

You can use iTunes for Windows to back up and update your iPhone, iPad, or iPod touch, and to sync content from your computer to your device.

You can also use iCloud for Windows to access your photos, contacts, calendars, files, and more across all of your devices.

Change settings and manage your account

• Choose Account > View My Account to view information about your purchase history, manage your subscriptions, change your payment information, and more.
• Choose Account > Sign Out to sign out of iTunes with your Apple ID and remove access to your content from iTunes.
• Choose Edit > Preferences to change things like your language, set restrictions, and more.

If you change your language in iTunes, you might have to quit iTunes and reopen it.
