#539671 Next, let's see if we can determine if the crash is happening in the AFV library or not. To do that, try running vPilot in either host mode or remote mode, without voice.

#539698 So that means it's a crash happening in the AFV library code. Can you post a new thread in the AFV forum with the screenshot that shows the error in clear detail?

#539700 This is actually a known issue, which can be fixed by downloading the Windows Media Feature Pack.

Unhandled Exception Retrieving the COM class factory for component with CLSID {F447B69E-1884-4A7E-8055-346F74D6EDB3}

This happens when using Windows 10 N or KN editions (for example on Parallels) because they do not contain the media foundation API's. Download and install ... n-editions to resolve the issue.
