How to find a Vista 5 dongle ID if it has rubbed off of the dongle.


Vista 5

Windows Command Window


The Dongle ID is required for locking TAC Vista licenses to a site dongle. Normally, the dongle ID can be found on the side of a Vista 5 licensing dongle. However, on older dongles, this number can rub off.  It is still possible to extract the dongle ID using the GetTACHLInfo.exe dongle utility software.


  1. On the Start menu, click Run.
  2. In the Run dialog box, type cmd
  3. Click OK.
  4. In the dialog box, go to the folder C:\Program Files\Schneider Electric\License Server (as default)
    NOTE: for TAC Vista 5.1.3 and prior, go to the folder C:\Program Files\TAC\License Server.

    Use command "cd.." for going to the parent directory and command "cd folderPath" for going to a child directory. Can also view items in the current directory by typing "dir".

  5. In the dialog box, type GetTACHLInfo (or GetTACHLInfo.exe) and press Return. The dongle ID is listed after "TAC_HL_ID=".
