If you purchase the Petroleum Refining Library, you will need to have the latest version of AnyLogic to work with the library. You can download it from the official AnyLogic website. If you order a ready-made model from us and do not need its source code, then you do not need AnyLogic. As a result of this development, you will receive a pre-compiled version of the model that can be run on any computer in your organization. However, editing the source code will not be possible in this case.
