Why download the OLI Engine in UniSim Design?

A common question arises from UniSim Design users is "Why do I have to download software from OLI Systems, Inc. if it is already available to me from the UniSim Design installation package?"

This is a good question. The answer is easy to understand. OLI continually updates both its databases with new data and updated data as well as continually updates the numerical engine. The version of the OLI Engine in UniSim Design you received from original installation package could be superseded by a more recent build from OLI. For example, version 9.2.1 of the OLI Engine for UniSim design available for UniSim Design R440. This was the version OLI shipped to Honeywell when UniSim Design R440 was being created for release. More recently OLI released version 9.2.3 which contained updated and new data sets not available in the original 9.2.1. If you needed this new data you would have to download the updated software directly from OLI Systems.

New installation procedure for the OLI Engine in UniSim

OLI Systems has combined the installation of the OLI Engine 9.2 (and later) for all the various versions of the OLI Engine in UniSim. Prior to version OLI Version 9.2, there was a separate installation file for UniSim R430 and R440. Now we have combined the installation into a single package, a universal install. This makes life easier for OLI Systems, Honeywell International and the IT groups tasked for installing our software.

Installing the OLI Engine

In this condition, we have two versions of UniSim installed with one version of the OLI Engine. In this example we will install the same OLI Engine for both versions of UniSim.

Only show detected or installed products

This check box is used when a non-standard UniSim installation has occurred. OLI may not be able to directly detect the software or an installation script is being written and UniSim was not available. In this case we can link the OLI Engine to a non-existent product for later installation.
