I am getting this error message while trying to install iTunes on windows 10. "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 vend

Try repairing Apple Software Update from the programs and features control panel, then remove it and see if iTunes will install normally.

Otherwise 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 theiTunes 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.
