There is a website set up for the Crystal Report for Peachtree. I have checked the website and it provides relevant information to your questions. There is also a Reseller page where you can see the options for becoming a reseller. Secondly, there are some details only the developer can provide. For that, I recommend using the contact form to obtain the details you need.
