development

When you encounter an error message indicating that the vcruntime140d.dll file is missing or not found while running an application like appserv-x64-9.3.0, it usually means that the application depends on the Visual C++ Redistributable library that contains this file. In the case of the error mentioning vcruntime140d.dll, it indicates that the application is looking for a development-specific version of the library (the d in the filename denotes the debug/development version).
