#Microsoft excel product key install

The computer on which you want to install the product.

The product CD or DVD, if the software came on disc.

Without it you can’t reinstall the software. If you've lost your Microsoft Office or Windows product key, you'll need to find it before you can reinstall the software suite. Most software programs require a product key as part of the installation process. However, the one common denominator is the need for the product key. Depending on which version of Windows or Office you are running there are different methods for reinstallation – all quite straightforward. One of the easiest ways to fix these problems is by reinstalling Windows.Īnd with Microsoft Office you may need to reinstall because you’ve got a new computer or you're trying to resolve a program error. There might be several reasons why you want to reinstall Windows, from fixing software problems to a slow running computer or maybe you’ve been a bit slack and practising good security has been low on your priority list, and your computer is riddled with viruses. However, you can recover your product license keys from the Windows Registry and it’s a lot simpler than you might think with third-party utilities.

So should you want to reinstall the software you could, on the surface, have a problem. But losing these discs is easy and once lost you no longer have access to the product key. Your Windows or Office software usually comes bundled on your computer, along with discs that contain the product license key.
