Hello ! Resources purchased from our store are accessible within Logos Bible Software. Luckily, it looks like you already have Logos 8! So you can download and install the software from https://logos.com/install. Once installed, you can find your book in your Library, accessed via the icon in the top-left of the software that looks like three books leaned against one another. You can find more information on navigating the Library at https://support.logos.com/hc/en-us/articles/360016752591-Using-the-Library Once the book is located in the Library, it can be previewed and then downloaded there by opening it with a left-click.
