If the laptop is refurbished, second user or Recovered unit the number may already be registere.
The sticker you are looking at may be for the windows Operating System installed on the unit.

From the 2007 microsoft office system,why do they keep on asking me to enter my product key?what is these product key and where can i find it.where can i find my 25 character product key?pls help.

The product key is either stuck onto the disc case with a orange sticker or comes as a separate slip of paper within the Office 2007 packaging usually inside the disc case. If your copy of 2007 was pre-installed when you purchased your machine the product key may have been stuck onto the top or side of the PC or on the underside of a laptop. Worst case scenario is that you have a legitimate copy of this software but the operating system has downloaded the Office Genuine Advantage update which has invalidated your software. There's a guide here that will help you uninstall the OGA update if this is what has happened to you.

I have bought a new laptop Acer Aspire 5542, I have tried to do some account and letters and everytime I open it tells me to put in the 25 digit number which is located on the bottom of the laptop the...

Have a close look at the numbers and letters with a magnifing glass. It is difficult to distinguish between 6 & G, 0 & O, 8 & B etc.
The 25 digit product code you have quoted could be for the Windows installation (the label states which product it is for) and won't work for MS Office. Is there another installation product code for Microsoft Office? It may be in your documentation.
Failing that you will need to contact Microsoft for a product installation code.

Hello the niangtonsing.

I've read your question a few times, and I infer something a little different each time ... but that's maybe my bad. However, here's a GEEK-steer I hope will provide the necessary joy ...

There are three potential sources/solutions for your key code:
  1. You should be able to locate the product key code (5x5, 25 digits long) on your MS Office 2007 installation disk/sleeve.
  2. If you've lost your disk/sleeve, you can contact Microsoft support services [800-MICROSOFT (642-7676)] for a no-charge resolution.
  3. HOWEVER, if the software is currently installed, there are many software applets that can present the key code to you, but I'll recommend "Belarc Advisor". Download/install and/or on-line run it, then after it process, it will display its report in your default web-browser. You'll then find your key code in the "Software Licenses" section.
NOTE: If the software was installed and registered on a computer other than the one your "girls" have it installed now and are trying to use, then you of course have a problem, as the EULA license typically only authorizes use on one computer (at a time).

Good luck, and thanks in advance for posting back ...

I need a 25 number to register software

This is a Product Key, This should be on the CD case,

If this is for MS word and you just bought the computer, Chances are you have a Trial version, Which the store loads on the Computer, To register another 90 Day trial goto and register the Product under your name
