Hi Jen Pranav is quite right. You absolutely must use JAWS 7.0 with J-Say Pro 3.0. However, you would not as he suggests be able to try J-Say out with a jaws demo because it is linked to your jaws serial number. So in summary you will need to 1. Remove the existing J-Say product installed on the machine. 2. install JAWS 7.0. 3. Install the J-Say authorisation. 4. Install J-say. Brian Hartgen
