- PCGen works on all operating systems – Windows, macOS, FreeBSD, and Linux.
PCGen doesn’t need a fast computer, and doesn’t need very much RAM. It will run on most computers made in the last ten years.
PCGen doesn’t take up much space. A full install is 150 MB.
PCGen requires Java 8 or newer.
Lots of other programs also use Java, so most computers already have Java installed. Otherwise, you can get Java from java.com.
