C:\Users\YOURUSERNAME\AppData\Local\FluxSoftware
If a prompt appeared saying that another program is using F.lux, it means that F.lux is still running in the background. You open the task manager, look for the running program named f.lux, right click and choose end task.
After making sure F.lux is not running anymore, try again to delete the F.lux folder in the Local Appdata folder.
