Staad.Pro License

Hi,

This is Surya Teja from Hyderabad, India.

Recently i purchased Staad.Pro license, While installing Staad.Pro it on my system PLANWIN, RCDC, STAAD FOUNDATION also installed.

I thought those are trial versions. But after activating STAAD.PRO with License key, the other products(RCDC, PLANWIN & STAAD FOUNDATION) also activated along with Staad.Pro.

Are those Chargeable ?? If so how to Deactivate it ??
