2 R255.3 PowerPoint presentations don't start running

[alexharrington]

PowerPoint presentations now load properly in 2 R255, but they don't play through the slides as expected.

If you manually start the presentation running, then the rest of the presentation runs respecting the timings in the slides, but something is preventing the first slide from advancing automatically.

Strange - we are passing straight to IE as before. I wonder if something has changed now in IE to prevent this from working.

This is reproducible in a very simple example WPF project with the following MainWindow:

namespace PowerPointViewer
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            WebBrowser browser = new WebBrowser();
            this.Scene.Children.Add(browser); // This is the name of the Grid in XAML
            //browser.Navigate(@"http://localhost:9696/2061.pps");
            browser.Navigate(@"C:\Users\Dan\Documents\Xibo Library\2061.pps");
            //browser.Navigate(@"C:\Users\Dan\Documents\Xibo Library\powerpoint.html"); // Serve via iframe
            //browser.Focusable = true;
            //browser.Focus();
        }
    }
}

Where the path is to any ppt/pps file. Initially I thought the ActiveX content was being blocked, but running it via a local browser should avoid that problem.

Opening up the same ppt/pps file in IE directly, and things work as they should.

Bug is still there on version R305.1 with Microsoft Office 2016 and Windows 10 1809. If I open pptx in IE11 everything is working correctly, if I'm using Xibo player presentation refuses to advance until I manually start presentation

Any updates on this? I believe I am impacted by after upgrading CMS to 3.3.2 and Windows clients to 3.307.00

Unfortunately there is very little we can do about this as the WebBrowser control for IE11 is end of life and the new alternative doesn't support embedding.

The best alternatives we know of are:

• If you have Office 360 use the option to embed in a webpage an copy the code into an embedded widget
• Save as a Video and use a video widget in Xibo
• EDIT: using the old v2 R203 player might still work

As before, if anyone knows of any registry settings or similar which solve this problem we'd be more than happy to include them, but as far as we know there aren't any.
