On the N (and KN) editions of Windows 10 and Windows 11, the Media Feature Pack is required but not installed by default.
To install it, go to:
Settings > Apps > Optional Features > Add a Feature (on Windows 10: Settings > Apps > Apps and Features > Optional Features > Add a Feature)
and select the “Media Feature Pack”.
Once installed, after rebooting, the Datastead products should work properly.

Note: if the Media Feature Pack is not listed (on older N releases), download it from:
