These are just a few of the fonts that are included in the pack but all together there are supposed to be 4,000 included and all you have to do is extract then go to the folder where they were extracted to. Its best to just go to the downloads folder and then right click extract here and the folder will be created.
Open the folder and inside should be all the fonts so select CTRL + A to select all and then right click and install and the rest is done for you. When your done installing them you can delete the extracted folder and you may want to hold on to archived file just in case.
