iTunes install/update fails Win 10 64 bit

I can't get the latest update to install on my win 10-64 machine. I get the following errors:

Event ID: 1013

Product: iTunes -- There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.

and

Product: Apple Software Update -- Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: SoftwareUpdate_UnregServer, location: C:\Program Files (x86)\Apple Software Update\SoftwareUpdate.exe, command: /UnregServer

Any suggestions?

Try repairing Apple Software Update from the Programs and Features control panel, then reinstall 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 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.
