Exception only in one PC, in others work fine

Question

I have an exception only in one PC, in others all work fine, anyone know wher it is comming from?

dditional information: Requested Windows Runtime type 'Windows.Media.Capture.MediaCapture' is not registered.

This exception is showing only in modern style apps (windows strore app) in windows 8.1. In WPF or Windows Form apps camera works fine. Code is fine, because in other pc work great:) i install system one more time, but the exception still showing up.

Answer 1

Looking at Microsoft's Windows Universal Samples (https://github.com/Microsoft/Windows-universal-samples/blob/e13cf5dca497ad661706d150a154830666913be4/Samples/SpeechRecognitionAndSynthesis/cs/AudioCapturePermissions.cs#L35) shows following piece of code

try
{
    // Request access to the microphone only, to limit the number of capabilities we need
    // to request in the package manifest.
    MediaCaptureInitializationSettings settings = new MediaCaptureInitializationSettings();
    settings.StreamingCaptureMode = StreamingCaptureMode.Audio;
    settings.MediaCategory = MediaCategory.Speech;
    MediaCapture capture = new MediaCapture();

    await capture.InitializeAsync(settings);
}
catch (TypeLoadException)
{
    // On SKUs without media player (eg, the N SKUs), we may not have access to the Windows.Media.Capture
    // namespace unless the media player pack is installed. Handle this gracefully.
    var messageDialog = new Windows.UI.Popups.MessageDialog("Media player components are unavailable.");
    await messageDialog.ShowAsync();
    return false;
}

So you have to install "Media player components".
