Can't update to windows 10
Have tried to update latest I Tunes to Windows 10 on my laptop, Get an iTunes error message saying "a prograam requires for the install to complete could not be run. Help!!!
Acer Aspire laptop-OTHER, Windows 10
With that particular error 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.
