Try statically linking the runtime libraries if you need to run a debug build on a PC that does not have Visual Studio installed.

That is because you don't have the DEBUG version of the C/C++ runtime on that machine, only the RELEASE builds. Debug builds are meant only for development and debugging. You should not install/distribute them, only Release builds. And you should install the appropriate redistributable with the VC++ runtimes.
