New Post: Installation MapWinGis.ocx rev 52393 . Error in Delphi

I have installated the mapwingis exe downloaded from here.
When import the activex component, delphi generates the Mapwingis_TLB.pas with the definitions, classes and methods, but raises a compilation error (E2008 Incompatible types) at:

property Owner[var t: SYSINT; var d: SYSINT; var s: SYSINT; var l: SYSINT]: PSYSINT1 write Set_Owner; on IGridHeader = interface(IDispatch), same error in:
property Owner[var t: SYSINT; var d: SYSINT; var s: SYSINT; var l: SYSINT]: PSYSINT1 write Set_Owner; of TGridHeader = class(TOleServer).

How can solve it?.

Delphi RAD Studio XE3, Windows XP SP3
