Do I need to uninstall RSIGuard before installing a newer version?
It is not necessary to uninstall RSIGuard before installing a newer version. The best way to get an update is to click the Help menu, and select “Check for RSIGuard Update”. This will automatically update you. However, if you have downloaded an update manually, you may wish to exit RSIGuard before installing the new version to avoid needing to reboot Windows.
