If running the CMS from the SMS, change the location and name of the CMS-Flow executable by clicking on "Edit" | "Preferences...", and then selecting the "File Locations" tab and then clicking on the box under the "Executables" column next to "CMS-Flow" box in the "Models" column. Enter the location and name of the executable and select "Open".
  • Note: For security reasons, the CMS executables are available for download in a zip file.
