How to determine our version of Q Apply

Does anyone know how to determine which version of Q Apply we're running? we have a Test DB2 replication server that's been offline for some time, and I'm trying to resurrect it. When I try to start the Q Apply service though I'm getting this error:

2013-05-09-09.57.00.165000 <browser::verifyMsgVersion> ASN7515E "Q Apply" : "ASN" : "BR00000" : The Q Apply program cannot process message type "ASNMQ_HEARTBEAT" of version "4".

Per IBM our version of Q Capture and Q Apply aren't compatible, but I'm unsure how to determine what versions we're running so I can upgrade it if needed.

Thanks.
