AIR File Icon (For Native Installer)

Hi,

I am generating AIR application as native installer (.exe). I want to have a custom icon for my .exe file.

I have specified the icons in application descriptor file as

<icon>

                    <image16x16>icon...</image16x16>

                    <image32x32>icon...</image32x32>

                    <image48x48>icon...</image48x48>

                    <image57x57>icon...</image57x57>

                    <image72x72>icon...</image72x72>

                    <image114x114>icon...</image114x114>

                    <image128x128>icon...</image128x128>

          </icon>

But this icon does not appear to be .exe file icon, It appears as application installed file icon. I want to have different icons for application installed icon (Application Icon) and separate icon for application installer (.air or .exe file custom icon)

Kindly suggest any solution
