Issues in Installing OCaml dkml distribution

I am installing OCaml i use these commands

winget install Microsoft.VisualStudio.2019.BuildTools --override “–wait --passive --installPath C:\VS --addProductLang En-us --add Microsoft.VisualStudio.Workload.VCTools --includeRecommended” winget install Git.Git winget install Diskuv.OCaml

the above installation was done. now next step is install dkml distribution , so i write following command

dkml init --system

and it is giving me error ‘dkml’ is not recognized as an internal or external command, operable program or batch file.

Can someone tell me what i am doing wrong, i am new to OCaml.

Did you close and re-open the command prompt?
