Include another app in ElectronJS | electronjs.org | Page 1

Heya guys,
I am currently creating a Electronjs App and there is a Button which Opena another App from the Folder. Which is a C# Application.

The tree looks like:

/softwares/
|
|
CsharpApp.exe
Csharpapp.dll
another.dll
another2.dll

And i use NSIS to Build my Application. If i "npm start" my C# Application will be open, when i click on "Open C# App" button in ElectronJS (html).
But when I build it (npm run builds), then it gives me a error when clicked on Button.

Error: spawn (electronapp/softwares/CsharpApp.exe) ENOENT

I sadly have no clue why it does not include the C# app in builder.

I would appreciate it, if someone finds a way to help. Thank you :)

    // Spawn a new process for the C# application

    csharpAppProcess.on('close', (code) => {
      console.log(`restarted application!`);

              Open CSharp Software

The folder (softwares)

ipcRenderer.js:

const { ipcRenderer } = require("electron");

document.getElementById('openCSharpAppButton').addEventListener('click', () => {
    ipcRenderer.send('openCSharpApp');
});

The Issue is, if I debug then It will work and open. but if I build it with NSIS, then it will return me a error

ERROR:

the blurred is the App name example "csharp.exe"
