Click on the red "M" shield in your taskbar, this opens up MSC and then click "Navigation", when the "Navigation Center" opens then click "About" under McAfee Resources to give you the version of McAfee in your computer. Your other 2 computers are still running the 2009 version, but they will eventually upgraded to the new 2010 version since you still have a valid subscription. You can put the new version on both of them sooner by uninstalling and running the MCPR removal tool. You would then login to your McAfee account and download the new software for each machine. The choice to do that is entirely up to you. Hope this answers your question.
Thanks so much for your very quick response. It was the correct answer to my question!
