3问题原因：VBA文件位置不同
有的是：C:\Program Files (x86)\Common Files\microsoft shared\VBA
有的是：C:\Program Files \Common Files\microsoft shared\VBA
而我两个位置都有VBA文件。所以我先把两个地方的VBA文件复制一份（怕搞错无法恢复），然后把两个地方的VBA6、VBA7.1 都试了一篇，最后成功了。
4VB核心代码：
Sub 保留表头拆分数据为若干新工作簿()
Dim arr, d As Object, k, t, i&, lc%, rng As Range, c%
c = Application.InputBox("请输入拆分列号", , , , , , , )
If c = Then Exit Sub
Application.ScreenUpdating = False
Application.DisplayAlerts = False
arr = [a1].CurrentRegion
lc = UBound(arr, )
Set rng = [a1].Resize(, lc)
Set d = CreateObject("scripting.dictionary")
For i = To UBound(arr)
If Not d.Exists(arr(i, c)) Then
Set d(arr(i, c)) = Cells(i, ).Resize(, lc)
Else
Set d(arr(i, c)) = Union(d(arr(i, c)), Cells(i, ).Resize(, lc))
End If
Next
k = d.Keys
t = d.Items
For i = To d.Count -
With Workbooks.Add(xlWBATWorksheet)
rng.Copy .Sheets().[a1]
t(i).Copy .Sheets().[a2]
.SaveAs Filename:=ThisWorkbook.Path & "\" & k(i) & ".xls"
.Close
End With
Next
Application.DisplayAlerts = True
Application.ScreenUpdating = True
MsgBox "完毕"
End Sub
