You can purchase most of our software for Windows through Gumroad.
Our Macintosh software only runs on older versions of OSX (El Capitan, Yosemite, Lion, Mountain Lion) and macOS 10.12 (Sierra).
After you place your order, we will contact you with a download link so be sure to provide a valid email. We can also provide all of our titles on a USB stick for an additional $10 charge. Site licenses are also available.
