Maddening! I'm setting up the new Lightroom after upgrading to Windows 10. At one point, it asks for Quicktime, but the link goes to downloader for Windows 7, which does not install in 10
Apple download site does not show a Quicktime version for Windows 10.
You can install it from the same link as It will work with windows 10 .
Please let us know if it helps.
You'll need to install an older version of Quicktime, 7.7.6. See this post: Re: Windows 10, quicktime lightroom and videos
