Export Metadata - TIKI unavailable

I want to set up the Export Metadata module, however I cannot turn the extractor TIKI to available. I have tried to download the latest .jar file and insert the path in the module.config.php but without success.
This is the step where I did something wrong, or maybe I did an error in the path:

TIKI
Used to extract many types of metadata from many types of files. Requires the Apache Tika content analysis toolkit. Java must be installed and the path to the tika-app-*.jar file must be configured in config/module.config.php under [extract_metadata_extractor_config][tika][jar_path].

Any ideas? Thanks!

Make sure you download a runnable jar, and not the source archive. Make double sure that the path is accurate. And, importantly, make sure Java is installed on your server.
