4.0 question
I bought 4.0 Nov 2009 for two computers. I also bought the cd at the same time. I have never done any upgrades since this version has worked fine and it is all I need. I now want to add a second computer. After reading some of the threads I'm confused. Several say a version as old as mine will not work on windows 7 64bit. That is what is on the computer I am using now. Why would it not work on the new one?
