Quicktime please install apple application support

I have installed the most recent version of Quicktime player on Windows 10. I need this to be able to play .MOV files. Quicktime has been working but has now stopped. I cannot find any information that makes sense to try and resolve this issue.

Windows, Windows 10

I have installed the most recent version of Quicktime player on Windows 10.

QuickTime for Windows is no longer officially supported since 2016. The last version was made for Windows 6 Vista and Windows 7; never for later Windows releases. On Windows 8 or later, only partial functionally works, through the Custom options of the installer.

Apple is not maintaining the Windows edition of QuickTime Player for any improvements or security that might be prudent after 2016. Apple recommends uninstalling QuickTime Player for Windows.


I need this to be able to play .MOV files.

Windows Media Player and other media player software (e.g VLC) will support MOV files without having QuickTime Player installed.

Select (quite old) third party video (editing) software may depend on software components from a QuickTime Player install. If that is the case, then please upgrade that software to a modern variant, to remove that dependency.

  • Modern MOV files would likely have H.264 AVC or H.265 HEVC video (or ProRes video) and AAC audio, for codecs (e.g. from iPhone recordings [**]), which are widely supported by most modern video software, although the H.265 codec may not be included in a default Windows 10/​11 install. (VLC has all its codecs internal and doesn’t need additional downloads, but other player software might need it.)
  • Old MOV files could use MPEG-4 Part 2 (MPEG-4 Visual/DivX/Xvid/H.263) video, DV video, or more esoteric codecs (e.g. Sorenson Video, Cinepak, Flash, Motion JPEG), which aren’t supported on modern macOS QuickTime Player either. Then a video conversion would be the recommended course of action.

You may check for codec use in video files by using MediaInfo or similar video file analysis software. Then you can know what (extra) is needed.


** iPhone 7 or later and iPad from that year or later (iOS 11 or later) can be configured to record in either H.265 (“high efficiency”) or H.264 (“most compatible”). For H.265 recordings, the files can optionally be converted to H.264 during initial offloading to a computer (“automatic”/​if needed vs. “keep originals”).
