Application.Visible: Invalid request. Hiding the application window is not allowed.

Hello everyone,

I'm currently working on a Java application that interacts with Microsoft PowerPoint using the JACOB (Java COM Bridge) library.
Here's the issue I'm encountering:
When I set the Visible property of the PowerPoint application to false, I receive the following error:

java.lang.RuntimeException: com.jacob.com.ComFailException: Invoke of: Visible
Source: Microsoft PowerPoint
Description: Application.Visible : Invalid request. Hiding the application window is not allowed.

Here's a snippet of my current code:

 ComThread.InitSTA();

    ActiveXComponent ppt = null;
    Dispatch presentations = null;
    Dispatch presentation = null;
     ppt = new ActiveXComponent("PowerPoint.Application");
//      ppt.setProperty("Visible", new Variant(true)); //only true can work
//      ppt.setProperty("Visible",false); //not work
//      ppt.setProperty("Visible", 0);  //not work
      presentations = ppt.getProperty("Presentations").toDispatch();
      presentation = Dispatch.call(presentations, "Open", pptFilePath, new Variant(false),
          new Variant(false), new Variant(false)).toDispatch();

Am I missing something?
Is there a better way to handle the visibility of the PowerPoint application window when using JACOB?
