Check on every startup: The check for new versions are performed each time CDGFix 3 Super is started.
Only check once a day: The check is only performed the first time CDGFix 3 Super is started any given day.
Only check once a week: The check is only performed when it is minimum seven days since the last check.
Never check for new versions: CDGFix 3 Super will not do any automatic checks for new versions.
Independently of the selected check interval you can always perform an ad-hoc check for new versions by selecting Check for new version now on the Options menu.
