>I build a form with a TreeView control in it. A few days ago somebody installs "something" in my pc, so now the TreeView reports me an error every time I try to edit the form with "modify screen". The error is 0x80040154 Class not registered.

Probably, the previous TreeView control was overwritten by the new instalation. Your form already contains an instance (in design mode) of the previous TreeView with, oleCID, OleClass and some other properties which don’t match anymore. If you manage to open your form try to drop a new instance of the treeview.

There are articles and threads here about adding Actives at runtime in order to avoid such things to happen.
