    What kind of BYOC is that? What command did you use to create/build the cloud?

    MSBuild logger comes bundled with Build Agent. If you providing that entire msbuild src\Setup.sln /t:Installers\Setup:Clean,Build ... command in your build script the path to a logger must be C:\Program Files\AppVeyor\BuildAgent\netfx\Appveyor.MSBuildLogger.dll
