The reason why the "Please install iTunes" error appears mainly because you are using the Windows Store's iTunes. It means, if your iTunes is downloaded from Windows Store instead of Apple's official website, then you will likely get this error when using our program.
Therefore, to make sure that you can use our software smoothly, you'd better download iTunes from Apple's official website. TuneFab Apple Music Converter is fully compatible with the latest version of iTunes.
If you have downloaded the latest version of iTunes from Apple's official website but still getting this warning note, please contact us.
