I recently had a new motherboard and I3 processor fitted and since then have been unable to open iTunes. Downloaded and reinstalled/repaired but to no avail. Any of you fundis out there care to help?
When you removed iTunes did you also remove c:\users\****\Music\iTunes - folder?
I had the issue where iTunes wasn't opening under Windows 10, i had to move the iTunes folder completely and let iTunes start from scratch then re-add my items.
