Unable to install F-Secure SAFE with error related to Windows 10 "S mode"


  • When I run the F-Secure install I have error, "For security and performance Windows 10 in S mode runs Microsoft verified apps...To get this app you need to switch out of S mode or find a similar app in the store."
  • Why am I unable to install F-Secure on my computer in S mode?


Windows 10 in S Mode is a more limited, locked-down Windows operating system. In S Mode, you can only install apps from the Store, and you can only browse the web with Microsoft Edge. F-Secure products are not available in Microsoft App store, so you need to get out of S mode to use our products.

If you purchase a PC in S Mode, you can leave S Mode for free. It doesn’t cost anything, but it is a one-time decision — once you’ve taken the PC out of S Mode, you can never put it back into S Mode.

How to Check If You’re Using S Mode

You can check whether you’re using S Mode by heading to Settings > System > About. On the About page, scroll down to the “Windows Specifications” section.

If you see the words “in S mode” to the right of the Edition entry, you’re using an S Mode PC. If not, you’re not using S Mode.
