XamlParseException on setting icon from xaml on WinXP/WinServer2003?

So... is strange, I have the follow code in my Window control for setting the window icon, which works prefectly on Win7 machine:

  Icon="./Resources/MyWPF.ico"

in

<Window x:Class="MyWPF.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    
    xmlns:mdi="clr-namespace:WPF.MDI;assembly=WPF.MDI"
    xmlns:misc="clr-namespace:MyWPF.Tools.Misc"
    xmlns:View="clr-namespace:MyWPF.View"
    xmlns:ScriptListView="clr-namespace:MyWPF.Tools.ScriptViewer.View"
    Title="Voysus System" WindowStartupLocation="CenterScreen" MinWidth="800"     MinHeight="600"            
    Icon="./Resources/MyWPF.ico"
    x:Name="_Root" Closing="_Root_Closing">

But then when it run on Server 2003 Standard x64/ WinXP Pro, both gives me error:

System.Windows.Markup.XamlParseException
Source: PresentationFramework
Message: Cannot convert string './Resources/MyWPF.ico' in attribute 'Icon' to object of type 'System.Windows.Media.ImageSource'. The image decoder cannot decode the image. The image might be corrupted.  Error at object '_Root' in markup file 'VoysusSystem;component/mainwindow.xaml' Line 8 Position 95.

   at VoysusSystem.ViewModel.LoginViewModel.<.ctor>b__2(String str) in C:\SandBox\MyWPF\MyWPF\Main\ViewModel\LoginViewModel.cs:line 97

I also tried to use Icon="/MyWPF;component/Resources/MyWPF.ico"

But it also gaves me same error.

After I remove the line, the code stop throwing exception on both WinXP and WinServer2003.

And again, these code is runs fine in Win7 and displayed the icon on the Window properly.

It happened to me once because used a high def full of color icon, which doesn't seem to be correctly handled by the XP clients. Reduced the number of colors for the icon and it worked.
