Lights Up! v1.1 will install and run on any version of Windows from Win98 to Windows 7.
At this time, the installer refuses to run on Windows 8. However, the program will still run if you can copy the installation folder (C:\Program Files\TerboSoft\Lights Up!) from an older machine. Just drop it into C:\Program Files (x86) on the Win8 machine and pin LightsUp!.exe to the task bar.
