Getting .NET Intergation Services working on Second Instance of ColdFusion 10

I'm running CF 10 Enterprise, with .NET integration services installed after the initial installation and configuration of the two instances. The instance names are "cfusion", the default, and we'll call the second one "instance2".

I installed .NET Integration Services through the standalone installer and chose c:\ColdFusion10\cfusion as the directory that it should install to. It created the jnbridge directory in the cfusion instance, and created the ColdFusion10DotNetService directoy. Running the following code under the fusion instance works perfectly:

<cfset UtilitiesProxy = "c:/inetpub/CFCs/MyCo/Integration/UtilitiesProxy.jar" />
<cfset CoStarUtilities = "c:/inetpub/CFCs/MyCo/Integration/MyCo.Utilities.dll" />
<cfset Paths = ArrayToList([CoStarUtilities, UtilitiesProxy]) />

<cfset Publisher = CreateObject( ".net", "MyCo.Utilities.Wall.Publisher", Paths ).init() />

Running the same code under instance2 gives me an error that The assembly that contains the class must be provided to the assembly attribute. This is the same error that I received before I got the .NET integration services working correctly under cfusion.

So what I need to find out is how to allow instance2 access to the .NET integration services. I've tried copying over the jnbridge directory to c:\ColdFusion10\instance2 and restarting the instance, but that didn't correct the problem. I'm under the impression that I'm missing some other piece of the puzzle since instance2 was created before the .NET Integration Services were installed.
