  1. Make sure the Sentinel drivers are installed.

3.1 Sentinel Driver Installation

The license drivers are usually automatically installed when installing Aimsun Next software, but if this is not the case then proceed manually as follows (in Windows):

  • Execute the setupClean.bat program located in the licenses\drivers\hasp folder.
  • A message will inform you when the drivers have been installed.
  • Restart your computer.

3.2 Checking the installation

Type the address "http://localhost:1947" in an internet browser such as Internet Explorer, Firefox or Safari.

This webpage informs users about the license status and will offer you some configuration settings.

If you received an error message such as "Page not found", please do the following:

  • Open the Task Manager
  • Click on Services
  • Click on Open Services
  • Look for 'Sentinel LDK License Manager'
  • If it is stopped please Restart the service

If the above does not work (if you cannot find the service 'Sentinel LDK License Manager'), this might be because the drivers were not properly installed. In this case, try reinstalling the Sentinel drivers.

3.3 Launch Aimsun Next

Launching Aimsun Next will automatically open the Aimsun licenser menu to acquire a license. For details about how to obtain or activate a license check the Aimsun Licensing section.
