Upgrading Oxymax for Windows v4.40 (~December 2009) or later simply involves uninstalling the existing version and running "setup.exe" from the new version. The configuration files necessary for each system are preserved on the removal of version of Oxymax 4.40 or greater and will automatically be used after the installation of a later version.

Users wishing to upgrade from a version of Oxymax for Windows older than 4.40 will simply need to move their configuration files (*.ini and *.exp) from their old installation directory (C:\Program Files\OxymaxWinV#.##\Config\) to the new installation directory (C:\Program Files\Oxymax\Config\).
