This is an intermittent problem with our 2008 installation, but certain computers are unable to open a part with out it crashing. It lists the MSVCR80.dll, but I have searched on that with no good information. I have tried uninstalling, reinstalling and nothing seems to work. I can open a drawing or assembly just fine, and I have no add-ins turned on. Has anybody else seen this? I am not sure if it has something to do with the uninstall of 2007 not being complete enough? We roll out a large number of installations via SMS (1101 this year), and can't have this happening once we go live. This definitely has been the most troubling installation, and we have been doing this for four years now.
