My CD does not work on my new computer. And on another one older, it works only for vocabulary and pronunciation, not for dialogs. It doesn't understand what I am saying.
Your product might be too old to support newer operating systems, therefore the cause to your issue. I've searched for this product and it doesn't appear to be available anymore. The developer's website that was previously used for Talk To Me is now pointing to Rosetta Stone.
You will have to acquire a new application in order to install it on your PC: http://www.rosettastone.eu/
