    VS110COMNTOOLS environment variable should be removed after VS uninstallation or should be updated after installation.I had installed VS11 RC to "D" drive and had uninstalled before RTM installation. I installed VS11 RTM to "C" drive and the variable still shows "D" drive for Tools folder(!). That's why i could not run code coverage on visual studio for two weeks and saw the error that you mentioned above..
