Thanks Mat. Yes the instructions were helpful. Seems my problem is I am not able to understand what I am supposed to put in the enter key.I presume that the serial number is the one on the disc envelope.Not sure where this goes so I have put it in where it says serial number which semems logic! The machine fingerprint I am not sure where I got that from. However wnen I go into Scan Soft Activation key confirmation I get The Activation Key could not be fetched. Invalid serial number. Enter a new serial number. So I am completely lost as to what numbers to put in and where. I have printed off the scansoft Product Activation.
