On the Start button on the bottom left of the Windows desktop, point to Settings, and then click Control Panel.
Double-click the Add/Remove Programs icon.
Click the version of Opus you want to remove, for example Opus Pro, on the Install/Uninstall tab, then click Add/Remove.
The uninstall program lets you perform an automatic or manual uninstall as required and will prompt you if you are trying to remove files which might be shared with other applications. You should only remove these files if you are confident they are not required, otherwise other Windows programs may not function correctly.
