I just installed windowblinds after purchasing it from humblebunle and after browsing wincustomize and trying a few skins nothing really suited exactly what I wanted, so I looked into how to make a skin myself. As far as I can tell from searching, I'm supposed to open windowblinds config, click the cog, and click "edit style in skinstudio". When I do that, it takes me to https://www.stardock.com/products/skinstudio/ and there is no download for it there. It says it's included in windowblinds for free, but I see no way of opening it. I've looked in the stardock folders and there's nothing resembling skinstudio, or any other editor.

Any help?
