This might happen if you have installed a different version of QuickTime from Apple in the past, perhaps as part of iTunes, and it hasn’t updated correctly. To fix it, open QuickTime from your Start Menu (it might appear as QuickTime Player or be inside a folder named Apple) and install any available updates through the Help menu. Your animation software should then be able to install as normal.
We have recently been advised that Apple has made some QuickTime updates unavailable. If you’re having trouble downloading QuickTime version 7.7, please try this alternate link.
HUE Animation for Windows will stop requiring QuickTime from version 1.6.2 onwards.
