How to Download and Install Microsoft 365 or Office 2021 on a PC with 64-bit Version

If you want to use the latest features and tools of Microsoft 365 or Office 2021 on your PC, you may need to download and install the 64-bit version of the software. The 64-bit version can handle large data sets, complex calculations, and high-resolution graphics better than the 32-bit version. However, before you start the installation process, you need to check some requirements and steps.

Check Your System Requirements

The first thing you need to do is to make sure your PC meets the system requirements for Microsoft 365 or Office 2021. You can find the detailed requirements on the Microsoft Support website. Some of the basic requirements are:

Download File:

  • A PC with Windows 10, Windows 8.1, or Windows 7 Service Pack 1.

  • A processor with at least 1 GHz speed and SSE2 instruction set.

  • At least 4 GB of RAM for the 64-bit version.

  • At least 4 GB of available disk space.

  • A screen resolution of at least 1280 x 768 pixels.

  • An internet connection and a Microsoft account for activation and updates.

Sign In to Download Microsoft 365 or Office 2021

The next step is to sign in to your Microsoft account and download the software from the Microsoft 365 home page. If you don't have a Microsoft account, you can create one for free. If you have a work or school account, you can sign in with that as well. Here are the steps to follow:

  • Go to and if you're not already signed in, select Sign in.

  • Sign in with the account you associated with this version of Microsoft 365 or Office 2021. This account can be a Microsoft account, or work or school account.

  • From the Microsoft 365 home page select Install Office.

  • Select Install (or depending on your version, Install Office>).

Choose the 64-bit Version

The 64-bit version of Microsoft 365 or Office 2021 is automatically installed unless Microsoft 365 detects you already have a 32-bit version of Microsoft 365 (or a stand-alone Microsoft 365 app such as Project or Visio) installed. In this case, the 32-bit version of Microsoft 365 will be installed instead. To change from a 32-bit version to a 64-bit version or vice versa, you need to uninstall Microsoft 365 first (including any stand-alone Microsoft 365 apps you have such as Project of Visio). Once the uninstall is complete, sign in again to and select Other install options, choose the language and version you want (64 or 32-bit), and then select Install.

Follow the Installation Instructions

After you choose the version you want, follow the instructions on the screen to complete the installation process. Depending on your browser, you may need to run, save, or setup the downloaded file. You may also need to accept the license agreement and enter your product key if prompted. Once the installation is finished, you can start using your Microsoft 365 or Office 2021 apps on your PC. 06063cd7f5
