Some computers come with a stripped-down version of Windows that only run simple apps, and will not allow you to install Excellerate
If you have that version, you can switch it to full Windows for free.
First, check to see if you have “Windows 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.
To switch out of S Mode to regular Windows, open the Store app on your PC and search for “Switch out of S Mode.” The Store will guide you through taking your PC out of S Mode.
Make sure you reboot your computer after that, then you can install Excellerate.
