Bad File Path errors when compiling CHM
Found the problem - MediaInfo.dll is installed in the Visual Studio bin/Debug directory by NuGet, but is not included when Visual Studio Setup creates the Primary output in VS 2019. It has to be added to the Setup files list and placed in the same directory as MediaInfrDotNet.dll and match the bitness (32 or 64 bit) of the project executable.
MediaInfoDotNet version is 0.7.79.40925
MediaInfo.dll not found after build
