ABBY Flexi capture 12 in WCF service

Hi.

I am using ABBYY Flexicapture SDK 12 for development of an OCR web service.

Web service is built with MS WCF technology.

I created also one small Windows forms app for consuming the WCF service. I send scans of front and back side of documents to the web service and in there OCR of the received images is done.

The problem is:

When WCF service binding is basicHttp, I get the following error in code:

System.Runtime.InteropServices.COMException Exception: Internal program error:
..\Src\Timer.cpp, 32

Event log writes two logs. One is titled DistributedCOM with message: The server {284CACFE-B6F2-461A-90C3-A7ACC8353816} did not register with DCOM within the required timeout.

The other one is titled: Service Control Manager with message: Service Connected Devices Platform Service ended because of the following error:
Unspecified error

However, if I configure the WCF binding with WSSecurity, SSL and certificate for client authentication, everything is working fine.

My costumers condition is that they dont want WSSecurity so please help.

Thank you in advance
