Thanks for that! Can you send me a picture of your “AppData\Local\Programs\Ultimate Vocal Remover\models\Demucs_Models\v3_v4_repo” folder (or wherever else you’ve installed the model) The error seems to think you have multiple models that begin with “97d170e1”.

Mine looks like this

Copy a single .th file into this directory. For this example I’ve used “97d170e1-a778de4a.th” and then copy “htdemucs.yaml”, paste the copy in this directory and rename it. I’ve renamed mine to “Cinematic_Sound_Demixing.yaml”
