Hi,

 

I recently purchased a refurbished L502X i7 laptop, so I also bought a copy of Microsoft Office Professional 2010 Pro. Ran set-up from the DVD and entered the Product Key and all went according to plan... Started up Excel and confronted with the Activation Wizard. Selected to Register via Internet and came back with, "This product cannot be activated because the product key is not valid".

I also used the Start Menu Option of "Microsoft Office 2010" utility, "This is not a valid Office Product Key".

The software was purchased from a Microsoft registered seller...

 

Any help gratefully received,

Barton.
