3.点击"标识"标签,选择"交互式用户"
4.点击"安全"标签,在"启动和激活权限"上点击"自定义",然后点击对应的"编辑"按钮,在弹出的"安全性"对话框中填加一个"NETWORK SERVICE"用户(注意要选择本计算机名),并给它赋予"本地启动"和"本地激活"权限.
5.依然是"安全"标签,在"访问权限"上点击"自定义",然后点击"编辑",在弹出的"安全性"对话框中也填加一个"NETWORK SERVICE"用户,然后赋予"本地访问"权限.
二、如果找不到Microsoft Excel 应用程序
1、进行OFFICE菜单中的组件重注册
2、如果仍未解决问题，点 开始--运行--输入EXCEL文件所在的路径 “c:\program files\exel.exe” /regserver 进行修复注册
参考：
这里有段VB6.0的，你可以参考。
注意添加引用。
Private Sub Command6_Click()
Dim i, j As Integer
Dim xlApplication As Excel.Application, xlWorkbook As Excel.Workbook, xlSheet
Dim xlApp As Excel.Application
On Error Resume Next
Set xlApplication = GetObject(, "Excel.Application")
Set xlApp = CreateObject("Excel.Application")
If MsgBox("确认将文件信息导出到EXCEL中？�", vbExclamation + vbYesNo, "警告") = vbYes Then
If Err.Number 0 Then Set xlApplication = CreateObject("Excel.Application")
Set xlWorkbook = xlApplication.Workbooks.Add
Set xlSheet = xlWorkbook.ActiveSheet
xlSheet.Cells(1, 2) = lblcl.Caption

先在: My Project 中引用 Microsoft Excel 11.0 Object Library（这个是Excel 2003，Excel 2007 是12.0）,之后在窗体代码中加入相关内容就行了。以下是一个窗体的简单实例
假设在C盘根文件夹中有：TEST.xls
Public Class 引用EXCEL窗体
Private A() As String = {"A", "B", "CC", "C", "D"}
Private B() As Integer = {1, 22, 34, 50, 16, 99, 14}
Private excelapp As New Microsoft.Office.Interop.Excel.Application
Private excelworkbook As Microsoft.Office.Interop.Excel.Workbook
Private Sub 引用EXCEL_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Index As Integer
excelworkbook = excelapp.Workbooks.Open("c:\test.xls")
excelapp.Application.Workbooks.Add(True)
excelapp.Cells(1, 1) = "数组:A"
For Index = 0 To UBound(A)
excelapp.Cells(Index + 2, 1) = A(Index)
Next
excelapp.Cells(1, 2) = "数组:B"
For Index = 0 To UBound(B)
excelapp.Cells(Index + 2, 2) = B(Index)
Next
excelapp.Visible = True
End Sub
End Class
运行结果：
数组:A 数组:B
A 1
B 22
CC 34
C 50
D 16
99
14
