No icons showing in XP while running an app developed in Vista

[ShadowUz]

Hello everyone. My MFC application is developed in Vista, VS 2008. But when I install it in XP and run it, there are no icons showing at all. Tested in Win 7 and Vista-all working fine. If anybody has any idea how to manage this problem, please, help. Thanks.

Are you talking about icons in a compiled resource file? What size/color depth do your icons have?

Thank you for your reply! Yes. In compiled resource. I made a Setup file and installed it both in XP and 7. As I said, in 7 it is working fine. Icon size: 32x32 color depth: 4 bit. It's a standard XP system icon. I have copied it from a XP machine.
