Hi @foxfen64 ,

sorry for the late reply. I also had this problem some time ago with the old Dragon Center installed. After I switched to the MSI Center, it works for me without problems so far.

I just tried it again on a fresh system. Here is what I did:

• Install the MSI Center (the link on that page doesn't work - you need to search for it in the Microsoft Store)
• Within this "awesome" app, install Mysic Light
• Start your IDE as administor (such that your runs have admin privileges)
• Make sure that you placed the DLLs in the right locations. The argument to MysticLightAPI#initialize(Path) should point to the project root.

I used this snippet for testing

public class NativeAPIExample {
	public static void main(final String[] args) {
		final MysticLight4j ml = new MysticLight4j();

		final String devicesAndLeds = ml.getAllAvailableDevices().stream()
				.map(d -> String.format("%s: \n%s", d.getName(), getLEDList(d)))
				.collect(Collectors.joining("\n\n"));
		System.out.println(devicesAndLeds);
	}

	private static String getLEDList(Device dev) {
		final List<String> ledNames = dev.getLEDs().stream()
				.map(led -> String.format("\t%s", led.getName()))
				.collect(Collectors.toList());
		return String.join("\n", ledNames);
	}
}

I hope this helps at least a little.
