FAQ Section: Download, Installation, First Start
  1. What do I do when the Installer says "Magic number did not match" ?
  2. WebStart stops with the error 'Wrong Certificate used to sign resource'
  3. Poseidon does not start. What do I do?
  4. How can I run Poseidon in a different language?
  5. How can I move/rename Poseidon's configuration directory?

    Poseidon's configuration is stored in several files in a common directory. (Poseidon does not alter the Windows registry in any way.) The name and location of the configuration directory defaults to:

    Windows
    C:/Documents and Settings/(user)/.poseidon/(edition-abbreviation)

    Linux
    ~/poseidon/(edition-abbreviation)
    where ~ denotes your home directory, usually /home/(your-name)

    To change this directory, set the environment variable named POSEIDON(edition-abbreviation)_HOME to the existing directory of your choice. Be sure to copy the directory contents to the new place to ensure that you do not lose your settings.

    Edition Abbreviations

    Community Edition CE
    Standard Edition SE
    Professional Edition PE
    Enterprise Edition EE
    Embedded Edition EmbEd
    Embedded Enterprise Edition EmbEE
    Use the startup scripts (/bin/poseidon(Mac).(sh/bat)) to start poseidon.
