Product Key not valid

I bought a Toshiba Satellite U20-S5057 with preloaded Windows Vista Home Premium. The product key in the sticker attached to the laptop is not accepted when trying to install the software.

    I have a new Acer Extensa 5420 with Windows Vista pre loaded and the product key on the bottom of the laptop is showing invalid. I have had multiple people try typing it in so human error is out of the question.

I think this is a "Branded code".
In other word is a key code valid only for OS retailed by Acer.
If you use another media CD (i.e. OEM CD) the key is not valid.
You can only use whith a Acer restore CD.

Now this is a License issue. Return your product to the Store since you paid for that software's License.
