I doubt if there is any compatibility with ver. 2 of EQ and Windows 7. You could go to EQ's web site and ask but seriously, windows has been through two updates (first Vista and now 7) and EQ has been drastically changed. It requires a lot of time and money to keep versions compatible through that many updates. Really you should consider just getting at least EQ 6 if you can't manage EQ 7. The difference between EQ5 and 6 was so dramatic and so worthwhile! The differences between 6 and 7, while wonderful, would not make me spend the extra money ifI didn't have it. I wouldn't even waste the time looking for version 2!
