Visual Basic 6 "ActiveX can't create object" Autocad 2007

I have a VB 6 app. that creates an autocad drawing from dimensional data entered by the user.  When the app gets to this line in the code "Set A2K = New AutoCAD.AcadApplication" I get the "ActiveX component cannot create object error."  Error 429.  The part that is odd is that if I run the application a second time the app runs fine with no errors.  If I wait a little while and run the app again the error returns and then the second time it runs fine again.  There must be something that is initialized the first time the Autocad dll tries to create a new acadapplication.  Does anyone have an idea on how to make this work on the first try?  Thanks in advance.

Have you tried? :
Dim A2K As AutoCAD.AcadApplication
Set A2K= CreateObject("AutoCAD.AcadApplication")

Or maybe until you find out what is wrong
On Error Resume Next
Set A2K = New AutoCAD.AcadApplication
If Error.Number = 429 Then
   'Try it again ..
   Set A2K = New AutoCAD.AcadApplication
End If
On Error Goto 0

Create Object doesn't seem to work.  I'm actually trying a different version of Autocad now.  Autocad 2008.  I've switched to a vb.net app.  I'm creating a browser based entry screen for dimensional data.  Now I'm able to get the app to run in debug mode but it gives me a "Retrieving the COM class factory for component with CLSID {} failed due to the following error: 80080005".  Any ideas on what needs to be changed in my security settings.  I've already enabled several things in the DCOM configuration.  Any help is greatly appreciated.

Not much exp. with .net but you could try
adding this:
 <identity impersonate="true" userName="Domain\MyUsername" password="MyPassword"/>
(a valid admin account on the server)
in web.config after <authentication mode="Windows" />

Already have the impersonate setup.  Back to using Autocad 2007.  I used your idea from above in the .net app.

         Try
            A2K = New Autodesk.AutoCAD.Interop.AcadApplication
        Catch
            A2K = New Autodesk.AutoCAD.Interop.AcadApplication
        End Try

Long pause first time through but hey it works.  Thanks for your help.

Thanks, wished it could have been a better solution than that. Ran across this link, seems they use GetObject first then try CreateObject. Might be worth a look.
