Error ASP 0177: 8007007e CreateObject fails for COM DLL

We have been trying to install a COM DLL on a new server. The interface is Classic ASP. The Map Connector DLL seems to be the problem but that is as far as I am able to get.

We are unable to get the pages served by IIS to give anything other than a 500 error.

When tracing the ASP:
