Using TMS Component pack in c++ builder 6


I am using TAdvStringGrid, TAdvSpinEdit, THTMLLabel in my project. I am adding the tmsc6.lib library to the project. and have specified the path in directories/conditionals.
But i am getting error "class TAdvStringGrid not found, create it", 
Please tell in detail how to use TMS Component pack with c++ builder 6.

Is the package TMSC6.BPR , TMSEXC6.BPR, TMSDEC6.BPR installed AND active in the IDE?
