How to clear cache in IE9 Windows7 using vbscript

I am trying to write the script to clear the cache on IE9 Windows7 (64 Bit). So far I have written below code. This code works fine on IE8 and Windows XP, but when I am trying to run same code on WIndows7 (IE9) it gives error by saying "Permission denied Line (39): "fso.DeleteFile (strWinFolder & "\Temp*."), True : fso.DeleteFolder (strWinFolder & "\Temp*."), True". "

Please check my script and correct me where I am doing wrong. Pardon me if I am wrong some where.

Dim methodName, fso, WshNetwork, WshShell, strVer, OSver, strWinFolder, strTempFolder, GetOS, strProfile, WindowsFolder, TemporaryFolder, NewFolder

Set fso = CreateObject("Scripting.FileSystemObject") : Set WshNetwork = CreateObject("Wscript.Network")

If InStr(OSver, "XP") Then GetOS = "WXP" : If InStr(OSver, "2000") Then GetOS = "W2K"
If InStr(OSver, "NT") Then GetOS = "NT4" : If InStr(OSver, "98") Then GetOS = "W98" 
If InStr(OSver, "Millennium") Then GetOS = "W98"

strWinFolder =  fso.GetSpecialFolder(WindowsFolder)
'strTempFolder =  fso.GetSpecialFolder(TemporaryFolder)

If GetOS = "WXP" OR GetOS = "W2K" Then
    Flag1 = True
    strProfile = "c:\Documents and Settings\"
Else
    Flag1 = False
End If
