ColdFusion 10 and COM Objects - I don't think it works!

I've been struggling with an implementation of ColdFusion 10 on a Windows Server 2008 R2 64 Bit server, with 32 Bit ColdFusion and IIS 7.5.

I cannot get ColdFusion 10 to instantiate any of the four COM objects that my company developed in house, they all report the same error:

An exception occurred when instantiating a COM object.              

  The cause of this exception was that: AutomationException:

However, these COM objects do work under the following scenarios:

CF 9.0.1 32 Bit on 64 Bit Windows Server IIS 7.5

CF 10.0.0 32 Bit on 32 Bit Windows Server 2003, ISS 6.0

I would like a sanity check here, just to confirm:

Has anyone been successful instantiating a COM object in the environment I describe (ColdFusion 10 on a Windows Server 2008 R2 64 Bit server, with 32 Bit ColdFusion and IIS 7.5).

If so, is it a publically available COM object so I can confirm?
