Problems with opening excel 2000

[ronin2307]

I use the following code to update an excel sheet:

Dim MyCommand As OleDb.OleDbDataAdapter
		Dim MyConnection As OleDb.OleDbConnection
		Dim DSExcel As DataSet
		Dim xlApp As Excel.Application
		Dim xlBook As Excel.Workbook
		Dim xlSheet As Excel.Worksheet

		If File.Exists("C:\temp.xls") Then
			File.Delete("C:\temp.xls")
		End If

		xlApp = CType(CreateObject("Excel.Application"), Excel.Application)
		xlBook = xlApp.Workbooks.Add()
		xlSheet = CType(xlBook.Worksheets(1), Excel.Worksheet)
		' Place some text in the second row of the sheet.
		xlSheet.Cells(1, 1) = "a"
		xlSheet.Cells(1, 2) = "b"
		xlSheet.Cells(1, 3) = "c"
		xlSheet.Cells(1, 4) = "d"
		xlSheet.Cells(1, 5) = "e"
		xlSheet.Cells(1, 6) = "f"
		'xlSheet.Cells(1, 7) = "g"
		xlSheet.Cells(1, 7) = "h"

		xlBook.SaveAs("C:\temp.xls")
		xlBook.Close()
		xlApp.Quit()

		Try
			MyConnection = New OleDb.OleDbConnection( _
						 "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\temp.xls" & _
						 ";Extended Properties=""Excel 8.0;HDR=yes;IMEX=0""")
			MyConnection.Open()

		 MyCommand = New OleDb.OleDbDataAdapter("SELECT * FROM [Sheet1$]", MyConnection)
			Dim cmdBuilder As New OleDbCommandBuilder(MyCommand)
			cmdBuilder.QuotePrefix = "["
			cmdBuilder.QuoteSuffix = "]"
			'MyCommand.InsertCommand = cmdBuilder.GetInsertCommand()

			DSExcel = New DataSet
			MyCommand.FillSchema(DSExcel, SchemaType.Source, "excel")
			MyCommand.Fill(DSExcel, "excel")

			For i As Integer = 0 To lstMain.Items.Count - 1
			    Dim dr As DataRow = DSExcel.Tables(0).NewRow
				dr(0) = lstMain.Items(i).Text
			    dr(1) = lstMain.Items(i).SubItems(1).Text
			    dr(2) = lstMain.Items(i).SubItems(2).Text
			    dr(3) = lstMain.Items(i).SubItems(3).Text
			    dr(4) = lstMain.Items(i).SubItems(4).Text
			    dr(5) = lstMain.Items(i).SubItems(5).Text
			    dr(6) = lstMain.Items(i).SubItems(6).Text
				DSExcel.Tables(0).Rows.Add(dr)
				dr = Nothing
			Next
			MyCommand.Update(DSExcel, "excel")
			MyConnection.Close()
		Catch ex As Exception
			MsgBox(ex.Message)
			MyConnection.Close()
			Exit Sub
		End Try
		MsgBox("DONE")
System.Diagnostics.Process.Start("C:\temp.xls")

This works great with excel 2003, but with excel 2000 it craps out. Basically what happens is the excel.exe process starts, but with it a process called AGENTSVC.exe starts as well and the whole thing just hangs. Does anybody know what is going on?
Thanx
