Setting Environment Variables on Windows

On Windows platforms, the installation program automatically sets all environmental variables, so no changes are necessary. However, if you must set optional variables or change defaults, use this procedure.

  1. On your desktop, right-click My Computer and select Properties from the submenu.
  2. Click the Advanced tab.
  3. Click the Environment Variables button.

    The Environment Variables dialog opens.

    1. If the environment variable does not already exist, click New and type the variable name and its value in the spaces provided; then click OK.
    2. If the variable does exist, select it from the list of System Variables or User Variables, click Edit, and make any modifications in the Variable Value field. Then click OK to capture the setting.
      Note: See the Microsoft Windows documentation for an explanation of user variables and system variables.
