The download assistant would not work on my Mac, so I downloaded all the files individually. Where should the iconica sketch.iso file be located so it works?
Welcome to the forum, @Gary_Winters. I suspect you need to double-click the .iso file to mount it, which will reveal the .vstsound files inside. Double-click one of those .vstsound files, which should launch Steinberg Library Manager and offer to install the content for you. Once the content is successfully installed, you can delete the .iso file.
Thank you Daniel.
