I've tried installing countless versions of quickset, but all of them turn up with "This Is Not A Supported System". My Fn keys seem to be fine for the most part, but the 3 quick keys at the top (one of setting, media browser/control or something, and one to turn off the screen) don't work when I press them (they only light up). They used to work until a few days ago. I already uninstaled quickset and tried to reinstal but that didn't work. Any suggestions?
System info:
Model: Dell Inspiron 5423
Windows 8 (64-bit)
