How to make the custom icon tranparent in MFC?

I have a small problem: I built an MFC application using MSVC 14.0 it works fine but somehow I wanted to change the default Icon so I added another icon to "res" folder and Named it as the main icon.
Now after build I get the new icon on my Dialog and in taskbar but it show the background! (white color) I need the background to be Transparent as the IDE does with my default MFC Icon.
After searching I had been suggested to use Image Editor on MSVC but I can't find that toolbar there! I only get the colors when opening the icon to edit in MSVC.
So how could I make the Icon background transparent? I used to use WINAPI where to use BitBlt but I don't know how here in MFC. Thank you.
- I also see that Toolbar Editor is grayed in Image menu.

In "Resource View", double click on the icon. Or, in "Solution Explorer" find"myapp.rc", double click it, and double click the icon. When you see the icon editor, go to main menu, click "Image -> Show color window" It shouldn't be gray unless the icon is read-only, or another program is editing the icon.

I don't know what the problem is. Just create a new icon and draw on it. Post a screen shot of this gray toolbar.

The icon/image editor in Visual Studio doesn't really support alpha transparency (32bpp), instead it does support 24bpp images, and you can set some portions of the image to be (fully) transparent, or inverse transparent. If this is OK to you fine, otherwise use an external editor. 32bpp images and icons can be included in your resources and compiled without problem; it's just the VS image editor that can't edit them.
