I purchased genuine office software a few years ago. I installed it on a new computer. After a couple of months I am getting notices that it is not genuine. But it is genuine. What is the problem?
If you buy OEM from one licence (60days demo and then full licence) it is alright - there is no right to reinstall it on another machine that it is activated first. If you buy FPP it is strange - call activation support (number will be in info box that was displays or in help).
