Once you have downloaded and extracted the files from the metadata archive, you should see two launch scripts in the root directory:
- MetaEditor.bat (for Windows)
- metaeditor.sh (for all other platforms)
Execute the script that is appropriate for your platform, either by double-clicking on the file name in an explorer window, or as a command from a shell or command prompt. You should see the initial Pentaho Metadata Editor workspace, as shown below.
