Hi Vishrut,

After downloading the license file, rename it to altair_lic.dat and place the same in the <installation directory>/security folder

If you have already done the above and still face the error, Use windows folder options / view > display file name extensions, to make sure the file is named altair_lic.dat and not altair_lic.dat.dat,

You need to confirm if the Ethernet address in the license file is the correct one and matches the one in your machine.

When you open the license file in a text editor you will see an Ethernet address there in a line that says 'ETHERNET =

The Ethernet ID is the ID of your machine which is exactly 12 hexadecimal numbers. For example D4WRF478F398

Run ipconfig/all in command window and check for physical address under Ethernet adapter local area connection:

The listed physical address under Ethernet adapter local area connection should be used to generate the license file, if there is no listing of Ethernet adapter local area connection, the address under Wireless Adapter LAN Wifi must be used.

That means if the address provided as above does not match the one in the license file, please request for the license file again with the correct Ethernet ID here https://studentedition.altair.com/

My License file is in the form of .dat only and in the right directory. Also the Ethernet address and Wireless Adapter LAN Wifi address are the same. What should I do now ?

It's NOT Ethernet (or Wireless) IP address, but the Physical address MAC (https://en.wikipedia.org/wiki/MAC_address)

So your Ethernet & Wireless cards have different address MAC, never the same!
