Hi Rick,Thanks for the info 👍 I am using IOS and Windows 8 at the moment,therefore I am only interested on Purchasing Mr Praiano IOS APP,and not taking the risk of purchasing or download anything free, which I am not familiar with,moreover,I am still in process of learning to understand more of windows 8.If you don't have an android or iOS device, or simply want the convenience of buying and using Praiano's app on your computer, there are a number of free android emulator devices that you can use. It's just like having an android cell phone in a window on your computer and from there you can open a Google app store account and purchase Gran Praiano 6. I just managed to set one of these up yesterday using "Bluestacks" and it works beautifully.
You need to have a Intel VT-x or AMD-V capable CPU (most are) and you need to go to your BIOS and enable that if it isn't already.
I don't want to sound like an ad for these guys, but they have downloads for Windows XP, Vista, 7 & 8 and MAC OSX. I looked them up on Wikipedia and they appear to be perfectly legit and aren't doing anything they aren't supposed to be doing.
