    A debug exe built with VS2017 (on windows 10), running on windows 7, has different dependencies than a release exe, and fails to run with this dll missing. However this dll does not exist on the windows 10 build machine. The project is set to target windows 8.1 with _WIN32_WINNT = 0x501 The release build runs OK, just not the debug build. dumpbin shows the release build does not have a dependency on ucrtbase, the debug build does. The release build depends on api-ms-win-crt L1-1.0 dlls instead. Does anyone know how to resolve this? There is nothing on the net, and it is stupid that you can't run a debug exe the same way one build with 2010 could be run.

      AFAIK, debug dlls are not supposed to be installed without VS.
