Excel with powershell and this big problem of locale

Question

Hi Folks, I'm getting C R A Z Y with this Excel/Powershell Stuff...
MY display language is EN
My input language is fr_CH
the following code : 
function Invoke([object]$m, [string]$method, $parameters)
$m.PSBase.GetType().InvokeMember(
$method, [Reflection.BindingFlags]::InvokeMethod, $null, $m, $parameters,$ciUS)
$ciUS = [System.Globalization.CultureInfo]'fr-CH'
$objExcel = New-object -com Excel.Application
$objExcel.visible = $True
$ci = [System.Globalization.CultureInfo]'fr-CH'
$objWorkbook = Invoke $objExcel.Workbooks Add
$objWorksheet = $objWorkbook.Worksheets.Item(1)
$objWorksheet.Cells.Item(1,1).FormulaLocal = "A value in cell A1."
Invoke $objWorkbook SaveAs "C:ScriptsTest.xls" > $null
Invoke $objWorkbook Close 0 > $null
$objExcel.Quit()
throw me the error : 
Exception calling "InvokeMember" with "6" argument(s): "Object does not match target type."
At line:3 char:1
+ $m.PSBase.GetType().InvokeMember(

The problem seems to be that PowerShell v1 for Windows Vista and PowerShell v2 CTP for all systems are storing the language neutral (English) help system in the en-US subfolder of the PowerShell folder.
On a localized versions of Windows, PowerShell seems to be looking for a subfolder with its own locale (e.g. de-DE for Germany, ru-RU for Russia, and so on) and does not fail over to en-US if the folder is not found.
RESOLUTION
Apply the language pack for your language so your local version of help gets added to the system.
If the language pack is not available, copy or rename the en-US folder to match your Windows locale. To learn your locale run the following command in the PowerShell prompt:
[System.Globalization.CultureInfo]::CurrentUICulture
