Troubleshoot problems while trying to activate Office 2007

[Emma.J]

Hi everyone,
I am facing a problem while installing the Microsoft Office 2007. Whenever I am trying to install an application I am getting the following error :

• Your software cannot be activated because the product key you installed with is not valid. Please uninstall the software and reinstall it using a valid product key.

I have inserted the proper key code, then also it is showing this error message. So I want some help from your side as soon as possible. Please tell me how to troubleshoot problems while trying to activate Office 2007?

This problem may occur if you installed an OEM copy of Office and if you have already installed and activated the same OEM copy on another computer. OEM copies of Office 2007 can be activated on one computer. You should know that you can remove and reinstall Office with the same product key on one computer. Some activation problems indicate that a file is damaged Opa12.dat to a 2007 Office product.

When you start a 2007 Office product that worked correctly before, an error message indicating that significant changes have been made to the configuration of the computer. Besides this error, you may also experience one or more of the following :

1. When you try to activate the product Office 2007 Activation Wizard disappears.
2. When you try to activate Office 2007 product on the Internet, an error message appears on the statement.
3. After installing Office 2007 suite, when you try to activate, the Activation Wizard does not start. No error message is displayed.

In such cases I would like to suggest you to replace the Office or contact to the Online service of Microsoft.

Sometimes it happens that when you try to activate the 2007 Office product by phone. However, after entering the confirmation ID provided by the support staff, you hear an error message indicating that the confirmation ID is invalid. When you start a 2007 Office product that worked correctly before, this product runs in reduced functionality mode. When you start an evaluation product Office 2007 for the first time after the activation process of licensing, product evaluation Office 2007 runs in reduced functionality mode and the Activation Wizard Microsoft Office appears. Some activation problems indicate that a file is damaged Opa12.dat to a 2007 Office product. In this case, a symptom experienced is that the product does not pass the Office Genuine Advantage validation.

If you try to install an OEM (Original Equipment Manufacturer) of a 2007 Office product on another computer, remember that you can install the OEM version only on a single computer. You must purchase a retail version of Office 2007 to another computer. Also verify that the settings for date and time are correct on the computer, which can be done in following manner :
Click Start, Run, type timedate.cpl, and then click OK. If the parameters of time or date is incorrect, correct them.
