PDFSplitMerge class not registered in Delphi XE

I have a system that uses Unit PDFSplitMerge_TLB , it compiles into a good one, but when executing and trying to use the TCPDFSplitMergeObj Object it says the class is not registered

Usage example:

procedure TForm1.BitBtn1Click(Sender: TObject);
var
  pdf: TCPDFSplitMergeObj;
begin

  pdf := TCPDFSplitMergeObj.Create(nil);
  pdf.SetCode('Your code here');
  ...
end;

It turns out that another machine works.

I saw Unit mention a file below

DepndLst: // (1) v2.0 stdole, (C: \ Windows \ SysWOW64 \ stdole2.tlb)

This file is in the windows folder so I researched it is a VB library so I do not know why it says the class is not registered

I'm using Delphi XE
