Sitecore Commerce Server profile definitions not found

Working inside the Commerce Server Manager, under the profile definitions I noticed a 404 not found page when selecting a definition (such as User Object).

Sitecore Commerce Server - profile definition not found

This was due to a local website binding being missing.

1. Open up IIS Manager
2. Select the default web site (or create this with an empty binding).
3. Create a virtual directory called Widgets and set the physical path to c:\Program Files (x86)\Common Files\Microsoft Shared\Enterprise Servers\Commerce Server\Widgets

The profile definition will now load correct without error.
