please do not put screenshots in here, and properly format your code snippets. This forums supports markdown, please make use of it. Thanks! You have to specify a URL when installing a plugin. If the plugin is stored locally already, you can use `file://` as a prefix. That said, running `elasticsearch-plugin install analysis-icu` should work out of the box, if you have an internet connection. ---

This works, now I know I was passing the wrong path and using the file:/// in wrong manner Unfortunately with the correct path, now I am getting an error from the plugin-descriptor.properties I executed the following command: `elasticsearch-plugin.bat install file:///C:/mypath/analysis-icu-7.3.1.zip` It gave me the following error: > Downloading file:///C:/mypath/analysis-icu-7.3.1.zip > [=================================================] 100% > Exception in thread "main" java.nio.file.NoSuchFileException: C:\Program Files\E > lastic\Elasticsearch\7.3.1\plugins.installing-1994739831823115814\plugin-descri > ptor.properties ---
