Installing the OLI Engine for Aspen PLUS

New installation procedure for the OLI Engine in Aspen PLUS

OLI Systems has combined the installation of the OLI Engine 9.2 (and later) for all the various versions of the OLI Engine in Aspen PLUS. Prior to version OLI Version 9.2, there was a separate installation file for Aspen PLUS V7.3.2, V8.0, V8.6, etc. Now we have combined the installation into a single package. This makes life easier for OLI Systems, Aspen Technologies and the IT groups tasked for installing our software.

There are two conditions which you may encounter when installing the OLI Software for Aspen PLUS. The first is the simplest in where a single copy of Aspen PLUS exists and you are adding or upgrading the OLI Engine software. The second is more complicated where you have multiple versions of Aspen PLUS Previously installed with multiple versions of OLI software in use. We will cover both conditions.

Installing the OLI Engine with previous version of OLI installed.

In this condition, we have several versions of Aspen Plus installed with several version of the OLI Engine. In this example we will install the same OLI Engine for all versions of Aspen Plus. The start menu may look like this:

This window shows you the intalled Aspen Plus programs. As you can see from the example we have versions 7.3.2, 8.0, 8.4 and 8.6 installed. The program has automatically installed each with the current version of the OLI Engine (for this example that is 9.2.1). The build date of the OLI Engine is also displayed which for this example is 04-December-2014.

If this is what you want, then you are done and you can click the Close button.


Link/Unlink All

This dialog has some options. The first major option is the Link All and Unlink All buttons. For example, there is an older version of the OLI Engine installed on this computer. This version is 9.1.4. If you wanted to downgrade quickly to see what the old version supplied you can do so quickly.

Click the Link All button.

Only show detected or installed products

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

Check for Updated configuration file

Clicking this link will poll the OLI Download Web Site for a new version of a configuration file. At some point in the future, Aspen Technologies will release a new version of Aspen PLUS (or change its name). At that time this configuration tool will be easily updated by downloading a small file.
