Error occurred while creating/connecting to automation server 0x80131500

Based on the number of matches on Google, this may be a candidate for the Tumbleweed award, but here goes...

I have a DLL written in .Net that is开发者_运维问答 exposed for reverse COM interop. There are several business objects and one object that exposes a method to call a web service via WSE3.

Using VBScript, all of the objects can be instantiated and used with no problem. However, I need to use the DLL from Progress. Doing that, the business objects are created just fine, but the object exposing the method to call the web service cannot be created.

The message is:

Error occurred while creating/connecting to automation server for: My.ClassName

Error code: 0x80131500 C:\PROGRESS\WRK\my.ped (5894)

Any thoughts?

If you haven't, try registering the dll's using regasm.

There are many entries in the Progress kbase (http://progress.atgnow.com/esprogress/Group.jsp?bgroup=progress) that seem possibly relevant. This one comes up #1:
