First, you need to make sure that you have a laptop made by ASUS, because the application will only work on those devices. If you do, try uninstalling and reinstalling the application and see if that helps.
In case this easy fix doesn't do the trick, press the Win + R buttons on your keyboard, then type devmgmt.msc in the Run box that open up and press Enter. In the Device Manager window that pops-up, make sure that your camera driver is installed correctly. If you see a yellow question mark on it, it means that it's not install properly, so right-click the name of the webcam and press Update. Lastly, reboot your computer and LifeFrame should work now.
In case you need to download the application again or drivers for your laptop, go to ASUS's support page, type in your laptop mode and go from there.
