You should consult the built-in manual to see how and where does the software export the recovered files. Also, this application is now discontinued, therefore I wouldn't recommend its installation or usage anymore.
Try installing something that really works, and it's also free. For example, Recuva might be a good alternative for this process. After you scan and find the images, right-click them, and select an output folder. This operation is available after it scanned the path you specified.
