VBS Invalid Character

This is a simple VBS script. But when I double-click on this, I get Invalid Character 800A0408 on Line 1, Character 1, which I think is the first "Dim". I am new to VBS--can u tell me what I did wrong? FYI, I have an XP OS and IIS6 Manager installed.

' This script adds the necessary Windows Presentation Foundation MIME types 
' to an IIS Server.
' To use this script, just double-click or execute it from a command line.
' Running this script multiple times results in multiple entries in the IIS MimeMap.

Dim MimeMapObj
Dim MimeMapArray
Dim WshShell
Dim oExec
Const ADS_PROPERTY_UPDATE = 2

' Set the MIME types to be added
Dim MimeTypesToAddArray = Array(".manifest", "application/manifest", ".xaml", _
    "application/xaml+xml", ".application", "application/x-ms-application", _
    ".deploy", "application/octet-stream", ".xbap", "application/x-ms-xbap", _
    ".xps", "application/vnd.ms-xpsdocument")

' Get the mimemap object 
Set MimeMapObj = GetObject("IIS://LocalHost/MimeMap")

' Call AddMimeType for every pair of extension/MIME type
For counter = 0 to UBound(MimeTypesToAddArray) Step 2

Set WshShell = CreateObject("WScript.Shell")

' Stop and Start the IIS Service

    WScript.Sleep 100
Loop

Set oExec = WshShell.Exec("net start w3svc")

' Report status to user

    ' Get the mappings from the MimeMap property. 
    MimeMapArray = M开发者_开发百科imeMapObj.GetEx("MimeMap")

    ' Add a new mapping. 
    i = UBound(MimeMapArray) + 1
    ReDim Preserve MimeMapArray(i)
    MimeMapArray(i) = CreateObject("MimeMap")
    MimeMapArray(i).Extension = Ext
    MimeMapArray(i).MimeType = MType
    MimeMapObj.PutEx(ADS_PROPERTY_UPDATE, "MimeMap", MimeMapArray)
    MimeMapObj.SetInfo()

End Sub

If you open the file with vim and use the ex command 'set list' it will show you any invisible characters that may be causing this issue.

Quoting http://classicasp.aspfaq.com/general/why-do-i-get-800a0408-errors.html

If you cut and paste code from other sources (e.g. web sites, other editors, etc) you often bring along characters that don't show up in Notepad but are, nonetheless, present -- or do appear as non-prinatable characters, that look like little squares. If you're looking at the line in question and it isn't simply an unclosed string or a premature carriage return, try deleting the line(s) altogether and re-typing them by hand. This should eliminate the possibility of 'invisible' problem characters mucking up the stream.

Check the encoding when you save the file, must be ANSI in NotePad
