Your error maybe the result of having Windows 10 Pro N edition installed without installing the Media Feature Pack from Microsoft. See this thread https://blueirissoftware.com/forum/view ... t=387#p984. I would also make sure you have installed Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 64-bit, see link https://support.microsoft.com/en-us/hel ... -downloads. Download and install vc_redist.x64.exe.
