Removing And Replacing Java

Due to a change in the license agreement for Java, it can no longer be used for free in business environments; this includes NDSU as well as State and County governments.  As a result it is necessary to replace it with an open-source (free) version known as Zulu OR purchase an official Java license for $30 from to stay legal.

For our on-campus computers we have deployed scripts intended to remove Java from each computer and, when possible, replace it with it's Zulu counterpart.  

For off-campus offices and anyone currently working from home, we strongly encourage you to check your computer to see if Java is installed.  Here are some instructions on what you'll need to do:

Locating And Removing Java

  1. Click on the Start button and then click the Settings Gear icon directly above it
    settings icon

  2. In the Windows Settings screen that appears, click on Apps
    apps button

  3. In the right pane, under Apps and Features, scroll down the app list to see if Java is listed.  Depending on your situation, there may be more than one installation.  The list should be in alphabetical order.
    Java apps

  4. If you do not see any listings for Java, you are done!  However, if you do find Java listed, please continue to step 5.

  5. Before removing Java, if you need Java to run some of your software, you'll want to make note of the version(s) so you can replace them with corresponding copies of Zulu later.  Be sure to also pay attention to whether it says "64-bit" in the name.  If it doesn't, it's a 32 bit install.

  6. To remove java, click on the Java app in the list to highlight it and then click on the Uninstall button that appears on the right hand side.  Do this for each one listed.

  7. When prompted, confirm the uninstall.  You will also get a second popup window asking you to approve changes to your computer.  Click OK.  

 

Replacing Java with Zulu

  1. Find your list of Java installations from step 5 above and visit the Azul Zulu download site.

  2. On the site, scroll down until you see the section titled "Download Zulu Builds of OpenJDK".

  3. Below this you can use the drop down menus to search for the version of Java you need:
    1. To the right of the drop down menus, select the "Older Zulu versions" switch to ensure all options are available to you.
    2. Select your Java Package (Java Development Kit (JDK) or Java (JRE))
    3. Select your Operating System (Windows)
    4. Now select your architecture (x86 32 bit or x86 64 bit).
    5. Finally select the version of Java (6, 7, 8, etc...).  Ignore numbers listed after the word "update".

  4. Once the list updates, select the top option and click on the green .msi button to download the installer.

  5. Once downloaded, run the .msi file and follow the on-screen instructions to complete the installation.
