Hello Eddy,
Why don't you advise the man to do a special upgrade and buy that one in the shop, is always a lot cheaper than the full version, and everything is legit.
The same with Windows Office, always buy the upgrade version in these cases.
To-days' money is not cheap for a lot of people, and I certainly like to pay once or go for an alternative if it is around. What is wrong to shopping around. And then there is the lite as well.
