This problem occurs because the computer may have some hotfixes installed that contained only System.ServiceModel.dll and not System.ServiceModel.WasHosting.dll. See the "More Information" section for a list of hotfixes that are known to contain only these files.

Because of this issue, the newer update cannot install the same version of both files. This exposes a dependency between the two files. This in turn causes the previously mentioned exception. This problem occurs because of an issue in previously released hotfixes and is not specifically caused by the new update. The new update merely causes the problem to surface.
