Launch AutoCAD 2015 from .Net process

I was trying to load AutoCAD 2015 from .Net process so that I can send commands to the document to create/modify blocks.

I tried both of these approaches but none of them seems to work.

1st approach:

AcadApplication app = new AcadApplication();
app.Visible = true;

2nd approach:

var t = Type.GetTypeFromProgID("AutoCAD.Application", true);
dynamic obj = Activator.CreateInstance(t, true);

In both of the cases I am getting COM exception. Any help?

It's not a duplicate as mentioned in comments, I have tried both approaches mentioned in here.

COM exception -

Retrieving the COM class factory for component with CLSID {0B628DE4-07AD-4284-81CA-5B439F67C5E6} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)).

Solution

  • Finally I was able to make it run for me. (Posting here so on one had to waste time like I did)

    Not sure what was an exact issue though. Strangely, running VS 2013 as normal user worked fine but in case I run it as an administrator, it always fails with above mentioned COM exception.
