How to get CPU serial number using HISE?

[Dan Korneff]

@ustk I've changed the preprocessor in the module like this:

Still the same result

[Dan Korneff]

It appears to be something with the exported plugin. The machine IDs generated with JUCE_USE_BETTER_MACHINE_IDS=1 are the same as if it's set to false. At least I know where to start looking

[Dan Korneff]

Ok... I've obviously have not had enough coffee today. I'd probably have to export the plugin after I rebuild HISE for something to take effect.
Ignore my stupidity for now.

@Dan-Korneff yeah it can be troublesome to be sure both are working (hise and plugin)

[Dan Korneff]

I'm using JUCE_USE_BETTER_MACHINE_IDS=1 in my new project. It's mostly working well, but I have a couple Windows 11 users that have to reactivate their license every few reboots. Is there a way to list the devices that are used to create this number so I can debug what is changing on their system?

[ustk]

@Dan-Korneff Ouch! As it doesn't respect what the name says, that is very unfortunate!

@Christoph-Hart I think this is the issue:
https://github.com/juce-framework/JUCE/commit/120f9266dc881c81371109c69b37a0a246accdeb

Is this fix already implemented?

@Dan-Korneff welp it‘s time for a JUCE_EVEN_BETTER_MACHINE_IDS macro…

You can fetch the MachineGuid that Windows creates on install using powershell. Here's how you do it in HISE:

const BackgroundTask = {};

BackgroundTask.getMachineGuid = Engine.createBackgroundTask("GetMachineGUID");
inline function getMachineGuid()
{
	local command = "reg";
	local args = 
	[
	    "query",
	    "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Cryptography",
	    "/v", 
	    "MachineGuid"
	];
	
	local logFunction = function(thread, isFinished, data)
	{
		if (!isFinished)
		{
			var id = data.substring(data.indexOf("REG_SZ")+6, data.length).trim();
			
			Console.print(id);
		}

	};

	
	BackgroundTask.getMachineGuid.runProcess(command, args, logFunction);
}

getMachineGuid();

A bit silly function naming since it won't return anything, but you get the gist.

@aaronventure I've created an app that displays the system ID with the Engine.getSystemID() function. I was looking for something that displayed the items in the system that were used to create the numbers.
Ultimately, it looks like there's a fix available from JUCE. Looking forward to the update
