SharePoint 2013 TIP: Cannot Co-locate SharePoint Designer and Office Web Apps

SharePoint Designer 2013 can be installed to your farm's existing Office Web Apps 2013 Server, and both Designer and OWA will function just fine.  However, updates to OWA will fail.  You will be able to install OWA updates, but you will not be able to rebuild the OWA server, after installing the updates.  In other words, this commandlet will fail:
New-OfficeWebAppsFarm -InternalURL "http://MyOWAServer" -AllowHttp –EditingEnabled
The reason for this is that SharePoint Designer employs Microsoft Office components.  A sparsely documented prerequisite of Office Web Apps 2013 deployment is that Microsoft Office (and Microsoft Office based products) are not installed.

To work around this, if you need to use the OWA server for SharePoint Designer, is to simply uninstall Designer, run the rebuild the OWA farm, and then re-install Designer. This will work fine until next month's patching.
