Hello MK,
Thanks for purchasing our theme.
Once you download the zip package from My Downloads on ThemeForest.
Kindly Unzip the package. Within that folder kindly navigate to this folder Emoll-v1-x-x >> Emoll-Premium-Multipurpose-Shopify-Theme >> Default Skin
Here you will be able to find all the actual theme variations we offer. Upload the zip file to Shopify from here.
Thanks.
