Go to your Windows Start Menu, open "This PC", and navigate to C:\Program Files (x86)\Fretlight Studio\Fretlight Improviser. Right click on the Improviser program, click on "Properties", "Compatibility", "Run this program as an administrator" and finally on "OK". Create a shortcut to the Improviser program and put that on your desktop to open the program moving forward as you will not be able to open the program through the Studio's interface.
