Microsoft Visual C++ Runtime Library + McAffe

I get this message when I tried to start Internet Explorer or the Explorer (using my account) if someone else is already logged in with a different login and already has opened one or both of those program (Internet Explorer or the Explorer). This problem does only pop up if I use McAffe. No problem with Kasparsky or Norton. I don´t like to go in to my wives account ant stop the programs she has opened every time I´m not the first to log in. Please help me.
