S Mode is enabled in the Home editions of Windows 11. S Mode prevents loading apps that are NOT available in the Microsoft Store, such as the Toontrack Product Manager. Fortunately, S Mode can be disabled.
To switch out of S mode, click here to open the Microsoft Store to the Switch out of S mode (or similar) page.
On the Switch out of S mode (or similar) page, select the Get button. After you see a confirmation message on the page, you’ll be able to install apps from outside of the Microsoft Store.
