It's impossible to say if it's compatible with Windows 10, because the website which provides this data is not working. I've tried to access it using the normal way, but the page loads in a loop. I've also used a proxy to access it and still nothing. It's not possible to say if the application works or not. If you still have the setup package, then launch it and check its behaviour. Alternatively, if you know it does have support for a certain version of Windows, right click it and go to Properties, then Compatibility. Select the OS from the list and launch the software as Administrator.
However, if the website comes back, use the following link to access it: http://www.freetelepromptersoftware.com/
