Altova UModel Professional Edition Licensing

If you need to discuss your licensing requirements for Altova UModel Professional Edition, please contact our Altova licensing specialists.

  • Installed User Licenses - Installed User licenses are purchased per number of computers on which you would like to install the software. For example, if you purchase a 10 Installed User license, you may install and use the software on up to 10 computers.
  • Concurrent User Licenses - A Concurrent User license allows you to install the software on up to 10 times the license number, provided that only the licensed number of people use the software at the same time. For example, if you purchase a 20 Concurrent User license, you may install the software on up to 200 computers and use it on up to 20 computers at the same time. All Concurrent User licenses must be used in conjunction with the Altova LicenseServer.
  • Named User Licenses - For each Named User license, you may install the software on up to 5 computers or workstations. This allows the user to switch from one computer to the other as necessary, provided that only one instance of the software will be used by the Named User at a time.
  • Multi-user Named License - Enterprises may purchase a single key code that will hold multiple Named User licenses. This saves you from having a separate key code for each Named User. Within the LicenseServer, the administrator assigns the individual named user a license according the user’s UPN (user principal name), i.e., his or her network ID. This is especially applicable for users working in a virtual environment. All Named User licenses must be used in conjunction with the Altova LicenseServer.
  • Virtual Environment - You may use Altova desktop software in virtual environments. These include a host terminal server (e.g., Microsoft Terminal Server or Citrix Metaframe), application virtualization server (e.g., Microsoft App-V, Citrix XenApp, or VMWare ThinApp), or virtual machine environment. You may use the software on a stand-alone personal computer and/or a persistent virtual machine (VM) with all license models. It is also permitted to use the software in a virtual desktop infrastructure (VDI) with non-dynamic network configurations, i.e., stable hostnames or IP addresses, with all license models. However, if you use the software on a terminal server or non-persistent VDI environment, or if your persistent VDI assigns dynamic hostnames, then you must use Named User licenses with the applicable Altova LicenseServer. All usage shall be within your internal network for the sole and exclusive purpose of permitting individual users within your organization to access and use the software. Use of Altova software in a virtual environment requires use of the Altova LicenseServer.
  • License Pool - For all Concurrent User and Named User licenses, you must use the Altova LicenseServer, and you may also use the LicenseServer to manage Installed User licenses. Concurrent User and Installed User licenses may be grouped on the same Altova LicenseServer, while Named User licenses must be used on a separate Altova LicenseServer. This is because Concurrent and Installed User licenses are allocated per machine, while Named User licenses are allocated per user.
  • Altova Closed Network LicenseServer (CNLS) - Atova Closed Network LicenseServer provides a central location for the management of licenses for Altova desktop products. Altova applications running in a network can have licenses assigned to them from the LicenseServer, thus giving administrators the flexibility to centrally manage and monitor licenses. Altova Closed Network LicenseServer is different than the online edition in that no mandatory connection to Altova.com is required.
