Hi Tom You can only install the token tool on your computer. If it's an Zip-File, you must extract it with Winrar, Winzip or whatever is used to zip it. The program makes tokens, which you have to upload on your roll20 library (Launch campaign, open art library, klick on the star (right of the search field) and you can upload your tokens). Keep the token names in mind! With search you can find them in the art library und drag them to the map. I'm not sure, if this area ist the right place for your question. Greetings, Daniel
