Qt app problems on non-development machines

I have a QT application that works as designed on my development (Windows7) machine. When it is installed on other non-development machines the app the will open and run, but it has problems. None of my in app icons, nor images display.

During installation, I am installing the QtCore4.dll, QtGuid4.dll, Microsoft_VC90_CRT_x86.msm and policy_9_0_Microsoft_VC90_CRT_x86.msm.

My application has a listview showing thumbnails of all pngs and jpegs in folders. I am using a separate thread to do this. Not even my default image png displays. Also in a simple QListWidget, none of the QListWidgetItem's icon display.

Any ideas on what I am not installing?

Thanks,

Yes! I was not including the imageformats folder with the corresponding dll's. Thanks sooooo much!
