Sage 300 comes with latest versions and new features every year and every version comes with latest features, sometimes we need to upgrade Sage 300 on our system as per requirement, and in this case, we need to reinstall Sage 300 to upgrade its version.

Sometimes when we try to uninstall and reinstall Sage 300, we get an error saying, “Failed to read SAU plugin folder from registry” and it doesn’t allow us to install Sage 300 on that system. Refer below screen shot.
