Hi,
Can you try to install the Media features ? http://www.microsoft.com/en-us/download/details.aspx?id=48231

What you suggested did not work, but I found the problem. IMMDeviceEnumerator::GetDefaultAudioEndpoint retuen ERROR_NOT_FOUND when there are no devices. I have Bluetooth earphones that are off when I'm not listening. When I turn them on, the program starts fine. To repro, disable all playback devices.

Hello,
I reproduce is issues and I check the error log. It seems that you do not have a working sound device.please check your sound device is fully working. Make sure you have working devices in your playback devices in Control Panel and set it as default. If it shows not plugged in. Please try to plug a earphone or cable to let your sound card working.

SaiYuen fixes this application crash by showing an error message if no audio interface is detected #15
You need to check your playback device in the Windows Control Panel
