Install LicenseServer (Windows)
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 setting (for upgrading to the newer version) 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.
For information about how to register and license DiffDog Server with Altova LicenseServer, see the section License DiffDog Server.
