WebSphere MQ - error running runivt on fresh install

Question

I am trying to execute the RUNIVT tests on a fresh install of Websphere MQ 7.5.0.2 for Windows, but hitting this error:

14/06/15 08:48:28 - Process(20900.1) User(bobble) Program(amqswsdl.exe) 
                      Host(bobblespc) Installation(Installation1) 
                      VRMF(7.5.0.2) 
AMQ9920: A SOAP Exception has been thrown. 

EXPLANATION: 
A SOAP method encountered a problem and has thrown an exception. Details of the 
exception are: 
'System.InvalidCastException: Unable to cast transparent proxy to type 
'MQSOAPHost'.    at MQWSDL.Main(String[] args)' 
ACTION: 
Investigate why the SOAP method threw the exception. 
----- MQWSDL.Main : 0 ---------------------------------------------------------

when the line:

amqswsdl "jms:/[email protected]&connectionFactory=(connectQueueManager(WMQSOAP.DEMO.QM))&initialContextFactory=com.ibm.mq.jms.Nojndi&targetService=StockQuoteDotNet.asmx&replyDestination=SYSTEM.SOAP.RESPONSE.QUEUE" StockQuoteDotNet.asmx generated\StockQuoteDotNet_Wmq.wsdl

is called.

I cannot find any detail on the error or why I might be getting it? Any assistance gratefully received!

I found this in the bin folder - it's the redirect for the XMS namespace...and redirects to a version I don't have installed? The WCF version redirects v6 & v7.0 to v7.5.

I don't know where or how this is installed - or where it's stored in Windows...but when I try and run any of the sample apps, they fall down as unable to load assembly v 2.5.0.2 of IBM.XMS
