When I bought my new HP desk top computer about a year ago (from Harvey Norman, Fyshwick, ACT) it was on display and was the last one left. They couldn't find the box it came in but I wasn't fussed. I soon realised that certain items that would
have been in the box weren't provided. This included the aforementioned Product key.
Never to mind because (inadvertently) I purchased separate Office Home and Student software. So, when I went to E-Mail an attachment MP Navigator EX 2.0, and I was required to insert my Product Key, I firstly downloaded the (additional) software and
then inserted the Product Key number shown on that package.
However, I'm continually informed that it's not a valid Product Key number. I don't know the original product key number, which was inherent in the machine when I bought it. However, I assume the new number is being overriden by the original
one.
What can I do?
