I had problems upgrading because the virtual machine would not start. I deleted VMWare Fusion and then installed version 6.
I did upgrade VMWare Tools. Since then I have been getting errors and warnings as indicated in Event Viewer>Application. Because of the errors and warnings, I reinstalled VMWare Tools and am still getting the VMWare Tools warnings and errors.
I am also getting errors and warnings for .NET Runtime Optimization Service, ASP.NET 2.0.50727.0, and System.ServiceModel.Install 3.0.0.0
