In order for DiffDog Server to work, it must be licensed via an Altova LicenseServer on your network. When you install DiffDog Server on Windows systems, you can install LicenseServer together with DiffDog Server. If a LicenseServer is already installed on your network, you do not need to install another one—unless a newer version of LicenseServer is required. (See next point, LicenseServer versions.)
During the installation process of DiffDog Server, check or uncheck the option for installing LicenseServer as appropriate. Note the following points:
•If you have not installed LicenseServer yet, leave the default settings as is. The wizard will install the latest version on the computer where you are running the wizard.
•If you have not installed LicenseServer yet and want to install Altova LicenseServer on another computer, clear the check box Install Altova LicenseServer on this machine and choose Register Later. In this case, you will need to install LicenseServer separately and register DiffDog Server afterwards.
•If LicenseServer has already been installed on your computer but is a lower version than the one indicated by the installation wizard, leave the default settings as is. In this case, the installation wizard will automatically upgrade your LicenseServer version. The existing registration and licensing information will be carried over to the new version of LicenseServer.
•If LicenseServer has already been installed on your computer or network and has the same version as the one indicated by the wizard, do the following:
oClear the check box Install Altova LicenseServer on this machine.
oUnder Register this product with, choose the LicenseServer with which you want to register DiffDog Server. Alternatively, choose Register Later. Note that you can always select Register Later if you want to ignore the LicenseServer associations and carry on with the installation of DiffDog Server.
•Altova server products must be licensed either with the version of LicenseServer that is appropriate to the installed DiffDog Server version or with a later version of LicenseServer.
•The LicenseServer version that is appropriate for a particular version of DiffDog Server is displayed during the installation of DiffDog Server. You can install this version of LicenseServer along with DiffDog Server. Alternatively, you can install LicenseServer separately.
•Before installing a newer version of LicenseServer, any older one must be de-installed. The LicenseServer installer will do this automatically if it detects an older version.
•LicenseServer versions are backwards compatible. They will work with older versions of DiffDog Server.
•If you install a new version of DiffDog Server and if your installed LicenseServer version is older than the appropriate LicenseServer, install the latest version of LicenseServer available on the Altova website.
•At the time of LicenseServer de-installation, all registration and licensing information held in the older version of LicenseServer will be saved to a database on your server machine. This data will be imported automatically into the newer version when the newer version is installed.
•The version number of the currently installed LicenseServer is given at the bottom of the LicenseServer configuration page (all tabs).
Current version: 3.7
