判断操作系统是32位还是64位：
Public Function OsBit() As Long
If Dir(Environ("windir") & "\SysWOW64", vbDirectory) <> "" Then
OsBit = 64
Else
OsBit = 32
End If
End Function
判断Office是32位还是64位：
Public Function OfficeBit() As Long
#If Win64 Then
OfficeBit = 64
#Else
OfficeBit = 32
#End If
End Function
测试代码:
Sub Test()
MsgBox "你当前使用的是 " & OsBit() & " 位操作系统，" & OfficeBit() & " 位Office！"
End Sub
