@dannytaurus My Friend, thank you so much! The 2022 version of visual studio is only available as professional. So I had to change my path.

Hi all, I scripted this License-Test in my Plugin and it works fine:

// -------------------------
// GUMROAD / TEST LICENSING
// -------------------------

const var LicenseField   = Content.getComponent("Label7");
const var ActivateButton = Content.getComponent("Button2");
const var Keyboard       = Content.getComponent("FloatingTile1");
const var LockOverlay    = Content.getComponent("Panel2");   // Overlay-Panel

var pluginUnlocked = false;


// -------- Plugin beim Start SPERREN --------
pluginUnlocked = false;

// Overlay aktiv → blockt alle Klicks
LockOverlay.set("visible", true);
LockOverlay.set("enabled", true);

// Keyboard zusätzlich sperren
Keyboard.set("enabled", false);

// Aktivierungs-UI aktiv lassen
LicenseField.set("enabled", true);
ActivateButton.set("enabled", true);


// ---------------- Button: Aktivieren ----------------
inline function onActivateButton(c, v)
{
    if (!v) return;

    local key = LicenseField.get("text");
    if (key == "") return;

    local TEST_KEY = "TEST-1234";

    if (key == TEST_KEY)
    {
        Console.print("Local test activation OK");

        pluginUnlocked = true;

        // Overlay weg → Plugin wieder benutzbar
        LockOverlay.set("visible", false);
        LockOverlay.set("enabled", false);

        // Keyboard wieder freigeben
        Keyboard.set("enabled", true);

        // --- ALLE Controls wieder aktiv ---
        Category.set("enabled", true);
        Variant.set("enabled", true);

        Attack.set("enabled", true);
        Hold.set("enabled", true);
        Decay.set("enabled", true);
        Sustain.set("enabled", true);
        Release.set("enabled", true);

        SaveButton.set("enabled", true);

        // Lizenz-UI verstecken
        ActivateButton.set("visible", false);
        LicenseField.set("visible", false);

        return;
    }

    Console.print("Wrong key");
}

ActivateButton.setControlCallback(onActivateButton);

Now I want to implement the auto-licensesystem from gumroad. Can someone help me to set up the right script for this? Gumroad License:

https://gumroad.com/help/article/76-license-keys

I would be very grateful if someone could help me with this. I want the buyer to have to activate the software only once. After that, no further activation should be required. The license should allow the user to cover 1-3 devices, and it must work on both Windows and Mac. Thank you in advance. Best regards.

@David-Healey oh, by myself I can't find it! Thank you David.

@dannytaurus My Friend, thank you so much! The 2022 version of visual studio is only available as professional. So I had to change my path.

I have really tried everything at this point. MSBuild is installed on my Windows system, but HISE simply cannot detect it, so I cannot proceed with the export. I urgently need help. I already tried multiple versions of Visual Studio and several restarts, but nothing works.

@David-Healey can you please check your emails?

@David-Healey OneDrive is local

@David-Healey ok, sorry with notepad it was possible to open it! seems like it's the right location

@David-Healey ah thank you! I finally found it, but I can't open it, too.

@David-Healey oh, I can't open the .ch1 files in my editor for some reason.
