Try www.zamzone.com for Bob Dancer's WinPoker 6, available free as shareware or with full features for $30. His analysis of hands and training mode choices helped my wife go from dismal to around 97% correct, and the game looks more like a Vegas machine than other VP games I have seen.
This game is also quite good and is a dead-on replica of the IGT poker machines. While it contains a feature to highlight the play that's the best, it doesn't contain the hand analysis features Winpoker has.
As with most software you are able to install it on a number of machines but if they are not for your private use it is illegal.
To install it on someones computer that hasn't paid to use it violates the law because it is a theft.
