GetObject(,"Int ernetExplorer.A pplication") unhandled exception

[mammucion]

Trying to automate processing 80,000 data sets through 15 web pages.
Application URL creates a new IE instance in which runs first a login form
and then runs the rest of the pages in the new window.

I can connect to a running Excel instance and obtain information from the
Excel DOM. I cannot do the same with Internet Explorer. However, I can
successfully create an new IE instance and manipulate it. Using an
application that has its own VB derived scripting language I get a similar
error.

Sample VB.NET code showing ability to connect running Excel instance,
Creating an IE instance and then failing to connect to the instance is pasted
below. No try/Catch block indicates the problem is in
microsoft.visua lbasic.dll. Any ideas or work arounds? VB prefered but I am
comfortable with C# and have used many other languages.

=== Output From Code as pasted ====
Excel: Renamed Sheet1
myIE.Name = Microsoft Internet Explorer
myIEDoc.url = http://www.yahoo.com/
Exception Message: Cannot create ActiveX component.

=== Output From code with no Try/Catch block ====
Excel: Renamed Sheet1
myIE.Name = Microsoft Internet Explorer
myIEDoc.url = http://www.yahoo.com/

An unhandled exception of type 'System.Excepti on' occurred in
