QuickTime won’t install on WINDOWS 10 By Orlando Mansur | August 30, 2015 2 Comments Try Installing QuickTime 7.7.6 for Windows… This version works! https://support.apple.com/kb/DL837?locale=en_US
Upgraded HP Laptop to Windows 10 and can’t get Quicktime to DL/Install. Tried QuickTime 7.7.8 for Windows but only for Vista & Windows 7.
Have you tried running in compatibility mode?
