Set menu icon for custom app

OK, So I recently got the portable apps menu and I love it. I also love how it recognizes other applications that are put into the PortableApps folder, even if they're not 'official' portable apps.
I did that with several of my stand alone programs, and now I want to use a more complex launcher.
I have the program's exe file and it does everything that it is supposed to, I don't need help with that.
I am trying to get a custom PortableApps menu icon and name to show up, but that won't happen.

here's the directory structure:

-Program
 program.exe (the file that I want to run)
    -App
     various files used by program
        -AppInfo
         appinfo.ini
         appicon.ico
    -Data
     other files used by program

I have added entries into appinfo.ini, and added appicon.ico, but they don't seem to affect how my program shows up in the menu.
Am I doing something wrong?

I'm not going to distribute this, so I don't want to make an installer and I'm not worried about all of the exact PortableApps protocol. I just want to change the icon and description that shows up in the menu.

I hope all of that makes sense.
