I had to change the location of the Setup.dll file (After these changes above it will be in the temporary folder).
It is also necessary to change just below by replacing in 3 lines.

ChangeFileExt(ExpandConstant('{srcexe}'), '.dll')

Replace with:

ExpandConstant('{tmp}\') + ExtractFileName(ChangeFileExt(ExpandConstant('{srcexe}'), '.dll'))

After the changes it will look like this;

  //....
  if FileExists(ExpandConstant('{tmp}\') + ExtractFileName(ChangeFileExt(ExpandConstant('{srcexe}'), '.dll'))) then
  begin
    if ISDoneInit(ExpandConstant('{tmp}\Records.inf'), $F777, 0,0,0, MainForm.Handle, 0, @UnpackDLLCallback) then
    begin
      if not ISArcExtract(0, 0, ExpandConstant('{tmp}\') + ExtractFileName(ChangeFileExt(ExpandConstant('{srcexe}'), '.dll')), ExpandConstant('{tmp}'), '', False, '', ExpandConstant('{tmp}\Arc.ini'), ExpandConstant('{tmp}'), False) then
      begin
        ISDoneError := True;
        SysErrorMessage(DLLGetLastError);
      end;
      ISDoneStop;
      UnloadDLL(ExpandConstant('{tmp}\ISDone.dll'));
    end;
    //...

Good luck!

Thanks man, really appreciate everything you've done!
