_IETagNameGetCollection return nothing

[jeremy.gilruiz@…]

The _IETagNameGetCollection function doesn't return elements on x64 editions.

My version of Internet explorer is : 8.0.7601.17514 64-bit édition

#include <IE.au3>

Opt("TrayAutoPause", 0)
Opt("TrayIconDebug", 0)

$Fenetre_IE = _IECreate("about:blank");, 0, 0, 1, 1)

For $Departements In $Departement

_IENavigate($Fenetre_IE, "​http://www.communes.com/rhone-alpes/ain/")
$Contenu_HTML = _IEBodyReadHTML($Fenetre_IE)
$BalisesLI = _IETagNameGetCollection($Fenetre_IE, "li")
For $BaliseLI In $BalisesLI

$Villes = StringRegExp($BaliseLI.innerhtml, '<a href="' & $Departements & '(?:.*?)_(\d{5})/">(.*?)<', 1)
If @error = 0 Then

consolewrite($Villes[0] & @TAB & $Villes[1] & @crlf)
FileWriteLine($DossierEnregistrement & "\Villes de frances.txt", $Villes[0] & @TAB & $Villes[1])

EndIf

Next

Next

_IEQuit($Fenetre_IE)
