FHWA Traffic Noise Model Version 1.1

FHWA Installing TNM 1.1 along side an existing TNM installation

NOTE: Installing this way will allow you to run both TNM 1.1 and your old version of TNM.

NOTE: This will require that you always run the new version of TNM through a shortcut.

  1. Backup "tnm.ini".

    This will be in your system directory, probably in something like "c:\winnt" or "c:\windows". To backup, just rename "tnm.ini" to "tnmxx.ini". Later on we will change this back.

  2. Start the TNM 1.1 installation

    This will bring up the "Welcome" dialog

  3. Press "Next" in the Welcome dialog

    This will bring up the "Choose Destination Location" dialog.

  4. You must install to a different location than where the old version of TNM is. Press "Browse" and choose a different location.
  5. Press "Next" in the Choose Destination Location dialog

    This will bring up the "Select Components" dialog

  6. Press "Next" in the Select Components dialog.

    Now all the files will be installed, and eventually the "Setup Complete" dialog will show up.

  7. Press "Finish" in the Setup Complete dialog.
  8. Rename "tnm.ini" to "tnm11.ini"

    Once again, this file should be in your system directory. The tnm.ini we are renaming here was the one just added by the installer. Each version of TNM needs a distinct INI file. The old version only looks for "tnm.ini" while the new version can be told to look elsewhere to allow for dual operation.

  9. Rename "tnmxx.ini" to "tnm.ini"

    This puts the backup of the old TNM INI file back where the old version of TNM can find it.

  10. Fixup the shortcut under the start menu
    1. Select Start | Programs | Traffic Noise Model | TNM Executable
    2. Right click on the TNM 1.1 executable shortcut and select Properties
    3. Click inside the Target edit field and go to end of text
    4. Add the following text: "-itnm11.ini"
      (include quotation marks, and make sure there is a space in front of the first quotation mark)
    5. Press OK (or APPLY and CLOSE)
  11. [optional] Create a shortcut from scratch to the new version of TNM
    1. Start Explorer
    2. Select a directory for the shortcut in the left-hand tree-view
    3. Go to File | New | Shortcut
    4. Press Browse, select new tnm executable
    5. In Command Line edit field, add the following text after the path to the new executable: "-itnm11.ini"
      (include quotation marks, and make sure there is a space in front of the first quotation mark)
    6. Press Next
    7. Select name for shortcut, TNM 1.1
    8. Finish
