This works exceptionally well for me.Using Windows 7, 64-bit, with 6 GB of RAM. My issue is with support. If you click on the "app support" button, all you get is an advertisement to buy one of the NaturallySpeaking products. No real tech support. Why would I download this app if I didnt already have one of their products? You call the Dragon support team you get someone who has trouble with English language and simply cannot get what the script. Unlike other microphones you may use with NaturallySpeaking, the iPhone mic does not permit changing all of the hotkeys in the options menu. This makes the numeric keypad difficult to use. This is a programming error that needs to be corrected. I want to be able to change the mic on/off hotkey to a null entry. Note how long it has been since an update. If you do a lot of financial data entry you will have to learn how to work around this problem.
