Imagelist not initialized?

Im getting this error on my listview, "Imagelist not initialized". It isnt happening on my computer, but at the clients end it is. Any ideas why this would happen?


edit*
forgot to mention, its happening when i try and add a reporticon:

VB Code:

lv1.ListItems(lv1.ListItems.Count).ListSubItems.Add , , , c

Is the OCX that contains the ImageList installed and registered on the client machine?

Well i guess, they are other VB6 devs..so it should work.

I have added them to the properties->custom->imagelist page of the listview..i cant see why it wouldnt work
