BUT -- Steve Dower seems to have identified that the wonders of dll hell never cease, and this isn't possible anyway. Oh well. I'm not entirely grasping what's happening here. There are multiple versions of msvcp140.dll floating around out there; what happens if one app requires one of them and another requires another? Can you simply say "take the newer one"? Is there a way to instantly recognize that there's a newer one available, and ignore the older one? Versioning is a pain.

Windows executables can and should ask for specific versions of the DLLs in the manifest (an XML file embedded in the EXE). Details here: https://en.wikipedia.org/wiki/Side-by-side_assembly
