之前写的代码 能够完整运行，现在去运行却出现了问题（调用失败）
代码示例如下：

Dim CATIA As Object
Set CATIA = CreateObject("CATIA.Application")
Dim productDocument1 As Document
Set productDocument1 = CATIA.ActiveDocument
Dim product1 As Product
Set product1 = productDocument1.Product
Dim products1 As Products
Set products1 = product1.Products

Text5.Text = products1.Count
Dim i As Integer
Dim ElementName(1 To 100), ElementPath(1 To 100)
For i = 1 To products1.Count
    ElementName(i) = products1.Item(i).ReferenceProduct.Parent.Name//
    ElementPath(i) = products1.Item(i).ReferenceProduct.Parent.Path   //
    MsgBox products1.Item(i).GetMasterShapeRepresentationPathName //这3句都报错：调用失败
Next

记得以前都可以运行的
请问是不是版本问题或者要下载补丁？感觉不应该是代码问题
还望指点  谢谢
