I've been looking for a way to change the camel icon from pp exe files , and after trying different things i made it work with freeware IcoFX 1.6 by creating a windows icon file with the following icon components :

- XP Colors
- 32x32, 32 bits
- 16x16, 32 bits
[download]

It may be trivial but all other settings i tried failed and that specific info wasn't available anywhere. HTH ;)
