AMD has released the latest version of the Ryzen Chipset Software, version 7.04.09.545, which introduces new bug fixes and adds new device IDs. The Ryzen Chipset Software drivers support AMD 300-series to 800-series desktop chipsets, as well as TRX and WRX series Ryzen Threadripper chipsets. The new version still includes several known issues that will hopefully be addressed in future updates, including the issue where after installing the AMD Chipset Installer version "7.xx.xx.xx", users cannot install older version "6.xx.xx.xx" or earlier drivers. Thankfully, there is a workaround detailed below. It also includes an issue where non-English driver names appearing in the English language selection and an issue with occasional failure to install or upgrade Ryzen PPKG.
