After installing the January updates for Office Communications Server 2007 R2 and publishing the new Communicator update to Client Version Filtering, I received an error that my client could not find the update.
I looked in the IIS logs and noticed that it was trying to pull the update for the x64 architecture.

Subsequently, my client was able to download and install the new Communicator update.
