Cannot open AutoCAD drawing from .NET

Hi:

 

This worked last week. Somehow it is no longer working now. I must be missing something. I need to open a drawing from VB.NET. Wheh I run this code, I get the following error:

A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in MakeSpoolFix.exe

 

Code:

Dim fullname As String = "L:\3105\310556A1.dwg"

Try

acadApp = GetObject(, "AutoCAD.Application.16.2")

Catch

acadApp = CreateObject("AutoCAD.Application.16.2")

End Try

acadApp.Visible = True

Debug.WriteLine(fullName)

Me.lblStatus.Text = "Running MakeSpool Fix on " & fullName & "..."

acadApp.Documents.Open(fullName, False)

acadDoc = acadApp.ActiveDocument

acadDoc.SendCommand("(wblockpurge) ")

 

Thanks in advance fr the help!

I dont know the answer to your problem but I can see another developing "AutoCAD.Application.16.2"

What happens when you upgrade your autocad and its now 16.3. Ok for testing but I would do a call to a routine that checks version numbers etc I have one sub that has version numbers in it and autoload it so available anytime. upgrade software upgrade 1 program only.
