Activating your license


There are two ways to activate your license:

·        Set the ALTAIR_LICENSE_PATH variable to point to where you stored your license file on your local drive

·        Place the license file in your Embed-installation-folder>/security folder and rename the file to altair_lic.dat



To set the ALTAIR_LICENSE_PATH variable


  • Press the Start button.
  • In the pop-up window, click on Control Panels.
  • Click on Systems and select Advanced system settings.
  • Select the Advanced tab.
  • Click on Environment Variables.
  • Under User Variables, select or create ALTAIR_LICENSE_PATH.
  • In the corresponding cell in the Value column, enter the complete path and file name for the license file; for example, C:\AltairLicenseFile\ALUS_ALUS_20151226_324178.dat.


     To place the license file in the install directory

      When using a local license file, without defining ALTAIR_LICENSE_PATH, you can rename the license file to altair_lic.dat and place it in the <Embed-installation-folder>/security folder

     Note:Many Window-based computers are configured with Hide Extensions for Known File Types activated. If your computer is configured this way, you should check the name of your license file after renaming it by doing the following:


  •       Open a Windows Explorer window
  •       Go to the license file folder
  •           Right-click altair_lic.dat and click Properties. The entire license file name is displayed.
  •       If multiple extensions are displayed, delete the unwanted file extensions and click OK.
