TeeChart Pro v3 installation errors

I have installed TeeChart Pro v3 in D4 Standard and tried to import it
with Components/Import ActiveX Control. A file named
\Delphi4\Imports\TeeChart_TLB.pas was created but the compiler stopped
with error messages, most of which are: Identifier redeclared ' '

Is the fault in my Delphi4 settings, or in TeeChart?
Please help...
