Thanks very much for all your feedback.
From what we can tell, one of our builds must have been missing a file "DWRCSHRegister.cmd". All you should have to do to resolve this behavior is to manually create the dwrcs folder on your local machine under your Windows Installation folder. For example: C:\Windows\dwrcs.
Once you manually create this folder on your local machine you should no longer see this error.
Your feedback is appreciated.
