editor - What does"'vi' is not recognized as an internal or external command, operable program or batch file." mean? -

While sending a mail using Mutt in windows I get an error saying: 'vi' Internally not recognized or external command, operative program or batch file. How to debug this error I have already installed Signin with the Sixth Package package. But it is not working!

This error message typically vi PATH Executable file was not found in any folder locations defined in the Environment variable.

To fix this, find the folder location of the vi executable file and add it to it.
