Can't initialize Simulation API in 2010

In 2009 I could instantiate the Cosmos/Simulation object using the code similar to this:

Dim SwApp As SldWorks.SldWorks
Dim cwApp As CosmosWorksLib.COSMOSWORKS
Dim cwAddin As CosmosWorksLib.CwAddincallback

Set SwApp = Application.SldWorks
Set cwAddin = SwApp.GetAddInObject("SldWorks.Simulation")
Set cwApp = cwAddin.COSMOSWORKS

Now, if I don't trap the error I get the following error on the last line.

"Run-time error '48': Error in loading DLL"

Does 2010 require a different string then "SldWorks.Simulation"?  I tried searching the registry.  It mentions a "SldWorks.Simulation.3", but that didn't work.  Thanks for any help.
