Problem with custom icons on components

Hello…
I’ve just finished my component.
Now i want to create a custom icon.
I followed this steps…
1º Created a FCustomIcons Folder
2º Import my 20x20 custom icon to library and placed in FCustomIcons folder
3º change the icon name to the name of component.

Everything works! when i open and close the FCustomIcons folder, my component refreshs the default component icon with my custom icon. So far everything ok…

the problem is, when im creating the SWC file.
After convert it and install the component with the mxp file.
After install it… i go to the Component (CTR + F7) and the icon that appears on my component is the default component icon those 3 color boxes…

Why does my custom icon doest apear!?
Any help!!?
