Office 2007 activation failed

[Deep123]

Recently i assembled a new Windows Vista Operating system. Today when i was trying to install Microsoft Office 2007, it installs but activation fails everytime. Also it gives me error message saying that I have reached the limit of computers on which i can activate the 2007 Office product.

I din't got exactly what that means. Do you guys have any suggestion regarding the same ? also help me out of the same.

I am not sure about the cause of this issue but some activation problems indicate that the Opa12.dat file is corrupted for a 2007 Office product. One such symptom is that the product does not pass Office Genuine Advantage validation.

In Windows Vista, the Opa12.dat file is stored in a different location than in earlier versions of Windows. To delete this file, you must first configure hidden folders to be visible. To do this, follow these steps:-

1. Click Start, and then click Computer.
2. On the Organize menu, click Folder and Search Options.
3. On the View tab, click Show hidden files and folders, and then click OK.

To delete the Opa12.dat file, follow these steps:

• Click Start. In the Search box, type %programdata%, and then press ENTER.
• Double-click the Microsoft folder.
• Double-click the Office folder.
• Double-click the Data folder, right-click the Opa12.dat file in that folder, and then click Delete.
• Important Do not delete the Opa12.bak file.
• Close the Windows Explorer window.
• Start a 2007 Office program to start the 2007 Office Activation Wizard.

Verify that the time and date settings are correct on the computer. You can do this by clicking on Start, than click Run, type timedate.cpl, and then click OK. If the time or date is incorrect, correct the time or date.

If you are trying to install an Original Equipment Manufacturer (OEM) version of a 2007 Office product on a different computer, be aware that you can install the OEM version on only a single computer. You must purchase a retail version of 2007 Office for a different computer.
