If Office still won’t install, check that your computer meets the system requirements to install Office. For example, you can’t install Office on computers running Windows XP or Windows Vista.

If you’re still unable to install Office following the steps in Download and install or reinstall Office try using the offline installer.

The Microsoft 365 offline installer may help bypass potential proxy, firewall, antivirus, or Internet connection issues that might occur during an Microsoft 365 installation.

Computers running Windows Vista or Windows XP don’t meet system requirements to install Office

Tip: If you discover you need an application that didn’t come with your Office product, you have the option to purchase a stand-alone application. For example, you may decide you need Access or Outlook, but those applications weren’t included in your product. To purchase a stand-alone application, go to https://products.office.com/ and do a search for the app you want to buy.
