Macro Is Checking Once The Prior Reference

I have checked the following reference whithin Excel VBA's references Manually:

Microsoft Visual Basic for Applications Extensibility 5.3

BUT when I run the following Macro, once checked the prior reference:

Sub AddModuleToProject()
On Error Resume Next
Debug.Print Err ' I GET 0
Dim VBProj As VBIDE.VBProject: Set VBProj = ActiveWorkbook.VBProject
Debug.Print Err ' I GET 1004
Dim VBComp As VBIDE.VBComponent: Set VBComp = VBProj.VBComponents.Add(vbext_ct_StdModule)
Debug.Print Err ' I GET 91
VBComp.Name = "NewModule"
Debug.Print Err ' I GET 91
End Sub
