OpenKM has many interesting features, but requires some configuration process to show its full potential.
Forum rules: Please, before asking something see the documentation wiki or use the search feature of the forum. And remember we don't have a crystal ball or mental readers, so if you post about an issue tell us which OpenKM are you using and also the browser and operating system version. For more info read How to Report Bugs Effectively.
You must compile the project.
The translation files are http://openkm.svn.sourceforge.net/viewv ... ient/lang/
If you give us the translated file will include on next OpenKM 5.X version on 5.1 ( newer version ) the translation it'll be more easy because all translations are on DBMS and can be imported and exported directly.
