At one of my customers I use the new BizTalk 2004 MSMQ Adapter. I read this Adapter is much beter in performance then the Out-of-the-Box MSMQT Adapter therefor I want to use this new Adapter. You can download the Adapter here

After the installation of the Adapter I wanted to send messages to a Private MSMQ. I get the following error :

The Messaging Engine failed to create the receive adapter "MSMQ".
Reason: "File or assembly name
Microsoft.Samples.BizTalk.Adapters.MSMQC.Runtime.dll, or one of its
dependencies, was not found.".

Microsoft Comment :

This is a bug, and here is the solution.
(1) Open your Adm_Adapter table in BizTalkMgmtDB database that your
Biztalk server is using.
(2) Identify the row with value of “Name” column be “MSMQ”
(3) Remove the value in the “InboundAssemblyPath” column (the current
value is C:\Program Files\Microsoft BizTalk Server
2004\SDK\Samples\Adapters\MSMQCAdapter\Run-Time\MSMQC\bin\Debug\Microsoft.Sa
mples.BizTalk.Adapters.MSMQC.Runtime.dll).
(4) Remove the value in the “OutboundAssemblyPath” column too if you
want the send side working.
(5) Restart the BizTalk host.
