Hi Richa,
Have you downloaded the
BIM Experience Kit or got the trial version from some other source?
If you're based in Bombay, Delhi, Hyderabad, Madras, Bangalore or Vizag, you can contact the
India reseller of ArchiCad and they'll send someone to your office and get things working for you:
BTW, ArchiCad 12 has just been launched so I wonder if a new version of the BIM Experience Kit is ready - or maybe that'll come later...
