11SP12 with MPP11.0R3 and CAD to PDF Converter

We installed Innovator 11SP12 and then installed the CAD to PDF converter.  It converts Solidworks to PDF in CAD documents no problem.

Then we installed MPP11.0R3 and created a simple process plan.

When we try to publish the process plan to HTML or PDF the conversion task fails.  The error is: 

Aras.ConversionFramework.Exceptions.EventCallbackErrorException: See inner exception for details: ---> System.Exception ---> System.Web.Services.Protocols.SoapException: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.IO.FileLoadException: Could not load file or assembly 'Conversion.Base, Version=11.0.0.6812, Culture=neutral, PublicKeyToken=524d880b05474146' or one of its dependencies.

I highlighted the part that seems to be the issue - the CAD to PDF installation updates the Conversion.Base.dll and ConversionManager.dll to version 11.0.0.6920 (from 11.0.0.6812).

Both files are in three locations on the server -

Innovator\Server\bin

Innovator\ConversionServer\bin

Innovator\AgentService\bin

Oddly, the Supprt Matrix at https://www.aras.com/SubscriberPortal/support.aspx shows that Innovator11.0SP12 supports MPP11.0R3 with hotfix-054618 (which says it is for Innovator11.0SP11) but the hotfix didn't help anything.

Does anyone have this working?  Any ideas?

Thanks!
