If you need to uninstall the Gear Software driver that comes bundled in older versions of Studio One, simply uninstall Studio One from the Windows Control Panel under "Programs and Features." The easiest way to do this is to type "Programs" into the search field in the Windows taskbar or Start menu, and select "Add or Remove Programs." Select Studio One and uninstall.
If you would like to run the Gear ASPI removal tool (GearAspi_remover.exe) that is provided by Gear Software, you can do so from the following link:
