What version of FileMaker? What operating system?
There's a folder inside the extensions folder named "labels". If it is missing you'll get this result.
You may need to re-install FileMaker to get the missing labels file.

Yes, you'll need to either re-install or copy this directory and the file within it from another computer where FilMaker has been successfully installed.
