Runtime 9 Error on computer but not on the other

I am getting a Runtime 9 error for the below on one PC but not on another. I did notice that there are other Menus listed on the PC that continues to get errors but not on the one working properly. Any suggestions?

                Set MenuObject = Application.CommandBars(1). _
                    Controls.Add(Type:=msoControlPopup, _
                    Before:=PositionOrMacro, _
                    Temporary:=True)
                MenuObject.Caption = Caption
