SAS Enterprise Miner Setup

Some classes at Emerson require the use of SAS Enterprise Miner analytics software. If you are in one of these classes, your professor will provide a link for you to download the software. SAS Enterprise Miner, which requires Java to run, does not work like most other software you may be used to. This guide covers how to set SAS Enterprise Miner up on your personal computer.

Tip: Use our computer labs

The computers in these labs are already configured for you to use SAS Enterprise Miner:

To get started in these labs, just download the file your professor gave you a link for, and double-click to open it.

The basic process for running SAS Enterprise Miner on your computer is:

  1. Ensure you're running the correct (and latest) version of Java.
    • You will have to uninstall any older versions of Java first.
  2. Download the main.jnlp file from the link your professor provided.
    • You must re-download the file each time you want to use the software.
  3. Open the downloaded file.
    • On a Mac, you will need to grant special permissions for this to work. We'll cover how to do this below.

Ensure you have the correct version of Java

  1. Check to see if a version of Java is already on your computer:

    • Windows: Look for Java using these instructions.
    • macOS: Select the Apple Menu > System Preferences, and search for a Java preference pane. It will likely be on the bottom row. 

    If you can't find any trace of Java on your computer, skip to Step 3: Install Java.

    If Java is already on your computer, continue to Step 2: Uninstall Java.

  2. Uninstall Java. Follow these instructions to ensure Java is completely uninstalled from your computer:

    Once Java is completely removed from your computer, you can move on to installing a fresh, current version.

  3. Install Java. Download the current version from the Java download page and run the installer.

  4. macOS users, ensure Java is set to keep temporary files:

    1. Select the Apple Menu > System Preferences, and open the Java pane.
    2. In the General tab, under Temporary Internet Files, click Settings.
    3. Make sure the box next to Keep temporary files on my computer is checked.

Download SAS Enterprise Miner

Use the link your professor provided to download SAS Enterprise Miner. The file you download will be titled main.jnlp.


The act of downloading this file essentially opens a new SAS session for you. Therefore, you must download a new copy of main.jnlp each and every time you want to open the software.

Open the downloaded file

This is relatively straightforward in Windows, but can be kind of tricky in macOS.


To open main.jnlp, either double-click or right-click and select Open With > Java™ Web Launcher from the context menu.

If this doesn't work, restart your computer and try this step again.


macOS has a security feature called Gatekeeper that makes opening main.jnlp less straightforward. First, you will need to attempt to open main.jnlp, then confirm that you want to open the software.

There are two ways to go about this: right-clicking (which is faster), or double-clicking (which is slower).

Right-clicking (faster method)

  1. Right-click (or two-finger click, with a trackpad) on the main.jnlp file to open the context menu. If you don't have right/two-finger clicking enabled, simply hold down control while you click normally.
  2. Click Open in the context menu.
  3. A dialog box will appear asking if you're sure you want to open the file. Click Open.
  4. Once Java starts running, it will also ask if you want to run the application. Click Run.

Double-clicking (slower method)

  1. Double-click the main.jnlp file.
  2. A dialog box will appear that says:

    "main.jnlp" cannot be opened because it is from an unidentified developer.

    There will be no option provided to proceed, so click OK or Cancel to close the dialog box.

  3. Immediately go to the Apple Menu > System Preferences, and open the Security & Privacy pane.
  4. On the lower half of the General tab, there will be a message about main.jnlp not being from an identified developer. Click Open Anyway.
  5. A dialog box will appear to confirm whether you're sure you want to open main.jnlp. Click Open.
  6. Once Java starts running, it will also ask if you want to run the application. Click Run.
