How to reinstall microsoft office ?
After purchasing Microsoft Office, activate and download the product. The packaging includes detailed instructions if you purchase the software from a retail store or order a key card online from a place like Amazon. If you order directly from Microsoft, you will receive the link in an email. There is an "Install Office" link on the receipt.
Step-by-step guide to install or reinstall Office on any Windows device :
Go to office.com/setup and sign in with your Microsoft account or create a new one.
Enter your product key (or activation code). This product key lets Microsoft know that the software was purchased legally. The key comes with any physical packaging you received and is included in the email if you ordered digitally. Select your country or region and also the language.
Select Install office.com/setup . After the installation file is downloaded, what happens next depends on which web browser you use. When you select Install, a dialog window appears at the bottom prompting you to run the file, save it, or cancel it. Select Run and work through the installation process.
If User Account Control asks if you want to allow the app to make changes to your device, select Yes.
Once you run the downloaded file, the installation process starts automatically. If Windows asks if you want to allow the installation, select Yes. If it prompts you to close any open programs, select Yes again.
When you see the phrase, "You're all set! Office is just installed," and an animation plays that shows you where to find Office applications on your computer. Select Close.
Microsoft Office is now installed and ready to use.
