Hi

I have both Vision 2010.1 for VS2008 and VS2010 installed on my PC, but I am only using the VS2008 version.  Since installing the latest version for VS2008, documentation no longer works and I get an ""failed to open registry key [Software\microsoft\msdn\9.0]"" error message.  How do I fix this or work round this to view the 2008 documention?

I have been using the 2010 documentation, but it contains features that don't appear to be available in the VS2008 version (specifically NFeatureCallback, I am trying to learn about maps and I'm a bit stuck!)

Thanks

Kevin
