Licensing at a Glance

  • Concurrent user

  1. Hottgenroth Software AG's product range includes ETU-Planer, HottCAD, Energieberater and heating, ventilation and air conditioning calculation software.[1]

  2. ETU-Planer uses a concurrent-user licence model: the workstation version can be installed on any number of computers, and the number of ETU-Planer instances running at the same time equals the number of licences purchased.[2]

  3. Hottgenroth's software maintenance contract states that the user acquires only a personal, non-transferable right of use, and that the contract renews for a further calendar year unless cancelled in writing three months before 31 December.[3]
