The DataLinker > Utilities menu comes from scripts that are installed in the InDesign "Scripts" folder. If that menu isn't showing up, there are two possible issues:
- There are permissions issues with the Scripts folder. If there is a DataLinker folder under the Scripts folder, then do a "Get Info" on the InDesign > Scripts folder and give yourself read and write access to that folder and all its subfolders. Then restart InDesign.
- If you still don't see the Utilities menu, try re-running the installer, Confirm that in the InDesign installation folder, under the Scripts folder, there's a folder called DataLinker.
