Ran into a problem that once I installed office 2010, my visual studio 2008 kept locking up when I was in the web page designer, searching the web I came across this blog post which gave the majority of the solution.

My differing situation was that I had removed office 2007 32bit to install office 2010 64 bit, so I didnt have the ability to restore, instead I had to delete it but once deleted everything works fine again
