Group Policy error: "The given Key was not present in the dictionary"

Consider the following scenario:
  • You create a new Group Policy setting and configure some registry items under Preferences (user or Computer). To do this, you use the registry wizard to add keys or values to the registry. For example, under Computer configuration \ Preferences \ Registry, you right-click and then select New -> Registry Wizard. This opens a user interface that enables you to manipulate registry items.
  • On Windows Server 2008 R2 and Windows Server 2008, you run the Group Policy Modeling Wizard against the new Group Policy setting. 
In this scenario, you experience one of the following symptoms, depending on your version of Internet Explorer: 
  • In Internet Explorer 8, you receive the following error message and error code 80131577: 
    An error occurred while generating report. The given Key was not present in the dictionary
  • In Internet Explorer 9, the wizard runs but does not report any registry settings. Additionally, the Registry Preferences section is empty.
There is a faulty registry item in the XML file that is associated with the Group Policy registry settings.
To fix this issue, re-create the Group Policy and registry settings. However, while you are using the registry browser to select values in a registry key, do not select the parent key together with the values in it. The parent key is auto-selected. This is, when you select a value in a key, a red tick appears automatically on the parent key folder. It is not necessary also to select the parent key.
