I meet same error and fixed when I install “Visual C++ Redistributable for Visual Studio 2015”: https://www.microsoft.com/en-hk/download/details.aspx?id=48145

I believe that for Windows installers this is now fixed. For the zips it is still not fixed, however. The question becomes to we want to keep this issue for tracking or no.
