The fast and smart ass answer is "On your HDD" but I think what you would rather have is an easy way to find the Program file. There are so many ways I don't know where to start. Ok. Go>start\my computer and then double click you Hard Disk Drive. It's usually C:\ It will show here. Or right click start then click "open all users" and there it is again. Or right click start then click "explore all users" and you will find it on the left. Whew. Ok here's another way go start\search\all files and folders and type in programs and then hit search. There are of course dozens of other ways to find it but these are about the most straight forward. Good luck.
