Windows batch command

I am using execute windows batch command to generate livingdoc documentation and it was working perfectly, after restarting jenkins it broke down and now in log it is showing me this error

it is written that “‘livingdoc’ is not recognized as an internal or external command,
operable program or batch file.” but it is installed.
can you guys help me?

Can you provide the pipeline you are using to run this? It sounds like the app is no longer in the path

I agree with @halkeye. You can inspect the PATH environment variable by adding the ‘set PATH’ command in your batch file. Is your app executable on any of the paths?
