Purchased at PC World and down loaded. I do have a 25 digit licence key
X18-15391-01 Is this what you mean?
This did not work. The message was as follows
I switched off and now that I have switched on again I am unable to operate Office 13
What further information do you need?
I have restarted my computer and Office 13 is shown on the programmes list but does not operate. It functioned when I tested it after the downloading.
