OnStartupComplete()

[Yael]

Hi,
I have a strange problem:
I created a com add-in for outlook 2003 in vs.net 2003 c#.
I installed this setup in 3 different computer, (toolbar add-in).
But in one of them I can't see me new add-in toolbar in the outlook.
I can see the eslse add-ins (like button add-in), but not this add-in
(toolbar).
In outlook:
tools-->options-->other-->advance option --> I can see me com add-in toolbar!
but not in the pane..even not in right click for add/move toolbar name..

public void OnConnection(object application, Extensibility.ext_ConnectMode
connectMode, object addInInst, ref System.Array custom){
MessageBox.Show("OnConnection()");
applicationObject =
(Microsoft.Office.Interop.Outlook.Application)application;addInInstance =
addInInst; if(connectMode != Extensibility.ext_ConnectMode.ext_cm_Startup)
{
MessageBox.Show("if(connectMode !=
Extensibility.ext_ConnectMode.ext_cm_Startup)");
OnStartupComplete(ref custom);
}
else
MessageBox.Show("else"); // in all the computers it's show this
}

public void OnStartupComplete(ref System.Array custom){
MessageBox.Show("OnStartupComplete()"); // It's not showing in the
"problem" computer!!!
CommandBars commandBars = applicationObject.ActiveExplorer().CommandBars;
}

In one computer I can see the toolbar add-in and I can see the
MessageBox.Show("OnStartupComplete()"); and MessageBox.Show("else");In the
problem else computer I can see only :MessageBox.Show("else");So ho is
calling to OnStartupComplete() if it is not inside to de if statment??

Thanking you in anticipation.
