The dialog controls correctly subscribe the "SelectionPath" event.
The event is fired after the folder selection is done (browse dialog).
Unfortunately there is a bug when retrieving the property value.

See "msi_dialog_handle_event":
http://source.winehq.org/git/wine.git/blob/e601ef55a9ce9c0d3e52da48846cfa3ff000a287:/dlls/msi/dialog.c#l693

--- snip ---
...
    else if ( !strcmpW( attribute, szSelectionPath ) )
    {
        LPWSTR prop = msi_dialog_dup_property( dialog, ctrl->property, TRUE );
        LPWSTR path;
        if (!prop) return;
        path = msi_dup_property( dialog->package->db, prop );
        SetWindowTextW( ctrl->hwnd, path );
        msi_free(prop);
        msi_free(path);
    }
--- snip ---

Due to "indirect == TRUE" passed to msi_dialog_dup_property(), the returned
string which ought to be the property name _is_ the property value (path value
of the INSTALLDIR property).
The following msi_dup_property() fails due to that mishap, returning NULL.

Either pass FALSE to msi_dialog_dup_property() or get rid following
msi_dup_property().

With that fixed, the installation directory name will be properly updated for
controls that are subscribed to SelectionPath event.
