Archive: icon doesn't show on XP

icon doesn't show on XP

Once, I configured the nsis script like following.

!define MUI_ICON ".\icon.ico"
!define MUI_UNICON ".\icon.ico"

when It is done to create installer, I can see the icon on the executive file.

However, I coudn't see the icon if the executive file exceeded 1.4G(not sure exactly).

Only, it is encountering on the Windows XP.

Is there any restrictions adding icon file to installer on the XP or was i something wrong ?

please advice me

Thanks in advance.
