When the Xena 6.0.0 windows installer is used and the user installing specifies to install "Only for me" then the version of Xena will not be written to the registry. This registry key is used by the Updater to compare if the version available from our website is newer than the version installed. The result is that when the user checks for updates they will see the same version they have (6.0.0) as available for update rather than seeing a message to say "Your software is up to date". This can be fixed by using a different method to determine if the local version is newer than the latest version on our website. This only involves changing the http://xena.sourceforge.net/updates.txt file that is used by the updater and project file that is used to generate this update file (in git://xena.git.sourceforge.net/xena/installers).
In testing have found that using the size of xena.jar works however this brings up a bug present with the updater. When called and there are no updates quite frequently an access violation results. This seems to be a known bug with the Advanced Installer:
