@SageLois When you run the installer, do you get the popup that says Windows protected your PC where you have to click more info and run anyway?
If you had a previous version installed, you may need to delete the settings and let them repopulate. Go to C:\Users\YOUR_USERNAME\AppData\Roaming\FeralHTPC\user_settings.json and delete the user_settings.json file. Restart the FeralHTPC app and see if it works.
