You cannot start it from a system command prompt or from File Explorer. Note You can start this tool only from a Visual Studio developer command prompt.

cl.exe can be run only on operating systems that support Microsoft Visual Studio for Windows. Start with figuring out what you want to do exactly (desktop? mobile? which platforms?) and install only the package you actually need. cl.exe is a tool that controls the Microsoft C++ (MSVC) C and C++ compilers and linker. You also have two versions of Qt there 5.7 and 5.8.Īll this is getting you nowhere and wastes a lot of your time and hard drive space. The C++ text editor also supports taking input from the user and standard libraries. Run the Visual Studio installer again and make sure you select C++ components.Īs for Qt - you installed Qt packages for all the supported versions of Visual Studio so to make them all usable you'd have to install Visual Studio 20. The user friendly C++ online compiler that allows you to Write C++ code and run it online. How did you install Visual Studio? Have you selected C++ components during installation or just went with the defaults? If I remember correctly VS installer does not have C++ selected by default (only the C#/.Net stuff).

The C++ compiler is missing (it's cl.exe). There should be a lot more files and folders in that directory. The Visual C++ installation directory doesn't look healthy. You don't know what you want to do? It's gonna be difficult to help you do that then )
