Fix: Error message ‘You have not entered a valid product key’ when you launch an Office application after installation

If after you have installed a Microsoft Office suite and you launch an Office application like Microsoft Word and you receive this error message ‘You have not entered a valid product key. Please check the number located on the sticker on the back of the CD case or on your Certificate of Authenticity‘ then this article might interest you.

This issue may occur due to one of the following reasons:

– You verified that the product key is correct.
– You installed a Microsoft Office suite from a retail box that you purchased from a retail store.
– You used the product key that appears on a sticker located on the bottom of your laptop or on your desktop case.
– You purchased and downloaded a Microsoft Office suite from an online website, such as Office.com.

To resolve this (applicable to the Microsoft Office 2010, 2007 and 2003 suites) do the following:

Method 1: Uninstall the additional Office suite and Office Activation Assistant

1. If you installed a Microsoft Office suite from a retail box that you purchased from a retail store, then open Control Panel. Then, open Add or Remove Programs or Programs and Features and verify if there is another copy of an Office suite installed in addition to the suite you have already installed.

2. Preinstalled Office 2010, 2007 or 2003 trial suites frequently conflict with the product key validation process. If you see an additional listing of an Office suite installed, such as a trial version or a version labeled “2007 Microsoft Office system”, then uninstall that suite and the Office Activation Assistant. Then, enter the product key again when you are prompted.

Note: You do not need to uninstall Office Activation Assistant if this item is not displayed in Add or Remove Programs or Programs and Features.

Method 2: Re-enter the product key

Step 1: Locate your Office suite product key
The 25-digit product key that you found on a sticker on the bottom of your laptop or on your desktop case is not the correct key. This key is the product key for Windows, not for Office. The correct product key for any Office suite will be in one of the following locations:

– Inside the retail Office box if you purchased your product from a retail store.
– In an e-mail message from the online Web site where you purchased the Office suite.
– On a sticker located on the outside of the CD case.
– On the inside of a Product Key Card (PKC) purchased at retail store (Office 2010 only)

Step 2: Re-enter the product key
Retail versions of the Office 2003, 2007 and 2010 suite are self-repairing. To repair the version of Office that is installed, start any Office application and follow the instructions to enter the product key. To do this, follow these steps:

1. Exit any programs that are running and close all open windows.
2. Start an Office application. For example, start Microsoft Office Word or Microsoft Office Excel.
3. Type the product key for the retail version of the Office 2003, 2007 or 2010 suite when you are prompted.

    • Hello,

      Did you purchase your copy of Office online? If so, you will find the PKC in an e-mail message from the online Web site where you purchased the Office suite.

      If you purchased your product from a retail store, you will find the PK inside the retail Office box.

      Cheers!
