Hello Mr Rana
I’m assuming you are not using an educational license.
If so, there are license packages (e.g. ASE4) that only contain the basic functions of TALPA, but without the 2-phase model for floors.
If you are interested in the 2-phase model, please contact your service partner. He or She will help you find the correct licence package for you.
Best regards
