Your app references the CRT as a DLL (e.g., msvcr140.dll ). This keeps file sizes small and allows the OS to update the library centrally, but requires the target machine to have the correct Visual C++ Redistributable installed. 3. Essential Security & Features

The Microsoft C Runtime has its roots in the early 1980s, when Microsoft first released its C compiler for MS-DOS.
