Ok... I am using Vista, and have been successful, so don't be too scared by the other posts. I did, however, have a problem with this download. For whatever reason, after waiting for it to download, I tried to install it and it informed me that the file was corrupt and needed to be downloaded again. Not knowing for sure whether the problem would repeat itself, I instead went to the Intuit download site and downloaded it from there (). You'll still need to purchase it from here to get the good price (the price on the Intuit site is $), but when I downloaded from there, the install went fine.

After reading several (over 100) reviews) I decided to purchase this program. It is well worth the money! Fitness 2012 has four different levels to start your program with as well as allowing you to choose your goals. It keeps a count of how many calories you burn and also will correct your form while doing your exercises. There are a multitude of exercises to choose from and several levels inside to keep you advancing. I have been using this for three weeks now and have to say I have been sore the whole time due to the incredible workouts it will put you through. If you buy it, be ready to have a workout! I would recommend this to anyone wanting to get back into shape or keep you in shape.
