Java Is Not Installed

If you attempt to launch the installation or upgrade program on a server that does not have a supported version of the Java Runtime Engine (JRE), an error message opens. You must install a supported version of the JRE, before you can proceed.

The error message reads:

"No Java virtual machine could be found from your PATH environment variable. You must install a VM prior to running this program."

Follow these steps:

1. (Optional) Determine which JRE version the server is running:
   1. Enter the following command at a command prompt or in a terminal window:

      java -version
      

      The command returns the JRE version that is installed.

2. Download the appropriate JRE installation file to the installation server.
3. (Windows) Run the JRE .exe installation file:
   1. Open the Run window: Select Start, Run.
   2. Specify the path and file name for the installation program in either of the following ways:
      • Click Browse and use the Browse window to locate and select the file.
      • Enter the path and the file name in the Open field.
      • Click OK.
   3. Follow the prompts to complete installation.
4. (Linux) Run the JRE .bin installation file:
   1. Navigate to the JRE .bin file location in a terminal window.
   2. Enter the following command:

      ./jre
      

      The JRE installation program starts.

   3. Follow the prompts to complete installation.
5. (Optional) Repeat step 1 to verify that the JRE version is updated correctly.
