Office Professional does not accept key

[Wendy]

Tried product key that came with the cd that shipped with
my new computer, but it tells me I don't have a valid
product key.

 

[Jerry]

Then go complain to those from whom you bought the computer.

 

[David ..M..]

Check closely your product key # was typed in correctly,
e.g difference between O and 0 etc.

 

[Brian]

Particularly watch for the differences between "8" and "B", "0" (zero)
and "O" (capital o).
