What can I say about this product. I cut my teeth on XP Pro, both at home and at work. Having got the XP Pro operating system I needed the Office XP Pro. Someone loaded the product up for me and told me it was genuine. They even gave me some disks. I discovered later that it was NOT genuine and so I needed a legal copy. I purchased an OEM and then discovered that my computer was VERY poorly. I purchased a new one, which came with Windows 7 and Microsoft's Office suite. I was having none of it. I loaded Office XP Pro almost immediately and I'm a very happy bunny.
So, I'd really recommend the product AND the supplier. Both as good as each other.
