Error when loading form designer in visual c++ 2008 express

I am using visual c++ 2008 express. When I try to open the form designer I
get the error:
Invalid class string (Exception from HRESULT: 0x800401F3 (CO_E_CLASSSTRING))
at
Microsoft.VisualStudio.Designer.Interfaces.IVSMDCodeDomProvider.get_CodeDomProvider()
at
Microsoft.VisualStudio.Shell.Design.Serialization.CodeDom.CodeDomDocDataAdapter.get_Provider()
at
Microsoft.VisualStudio.Shell.Design.Serialization.CodeDom.CodeDomDocDataAdapter.get_CompileUnit()

Microsoft.VisualStudio.Design.Serialization.CodeDom.VSCodeDomDesignerLoader.PerformLoad(IDesignerSerializationManager serializationManager)
at
Microsoft.VisualStudio.Design.Serialization.CodeDom.VSCodeDomDesignerLoader.DeferredLoadHandler.Microsoft.VisualStudio.TextManager.Interop.IVsTextBufferDataEvents.OnLoadCompleted(Int32 fReload)
Everything's fine apart from that. I think it's an error with the registry
permissions or I could be missing a reg key because I've had problems with
visual basic and c#. I've contacted microsoft customer services and they told
me to ask here and look in the knowledge base, which doesn't have the answer.
Can anyone help? Thanks.
