Uninstall the current illegal office first, thence install the new one 
Cos the key that you buy right now might not be able to match/activate the fake office that already installed, even it match but you need to change the settings (at least enable update function)...
And the clean install won't affect any current office file which were stored in the PC, why not use the most simple and easy way |
