Sign in to download Microsoft 365 or Office 2024 on a PC
Go to m365.cloud.microsoft/apps and if you're not already signed in, select Sign in.
Sign in with the account you associated with this version of Microsoft 365. This account can be a Microsoft account, or a work or school account. I forgot the account I use with Office
After signing in, follow the steps that match the type of account you signed in with.
You signed in with a Microsoft account
From the Microsoft 365__Apps__ page select Install apps.
Select __**Install**__ (or depending on your version, __**Install apps>**__).
__**You signed in with a work or school account**__ 
From the home page select __**Install apps**__. (Or, you might need to select __**Apps**__ from the left navigation pane, and then select __**Install apps**__.)

Select __**Microsoft 365 apps**__ to begin the installation.
The 64-bit version is installed by default unless Microsoft 365 or Office detects you already have a 32-bit version of Microsoft 365 or Office (or a stand-alone app such as Project or Visio) installed. In this case, the 32-bit version of Microsoft 365 or Office will be installed instead.
To change from a [32-bit version to a 64-bit version](https://support.microsoft.com/en-us/office/choose-between-the-64-bit-or-32-bit-version-of-office-2dee7807-8f95-4d0c-b5fe-6c6f49b8d261?wt.mc_id=SCL_InstallOffice_Home#) or vice versa, you need to [uninstall](https://support.microsoft.com/en-us/office/uninstall-microsoft-365-or-office-from-a-pc-9dd49b83-264a-477a-8fcc-2fdf5dbf61d8) 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 [m365.cloud.microsoft/apps](https://m365.cloud.microsoft/apps) and select Install apps. From the Install apps window select the language and version you want (64 or 32-bit), and then select __**Install**__. (See [Install Visio](https://support.microsoft.com/en-us/office/install-visio-or-access-visio-for-the-web-f98f21e3-aa02-4827-9167-ddab5b025710) or [Install Project](https://support.microsoft.com/en-us/office/install-project-7059249b-d9fe-4d61-ab96-5c5bf435f281) if you need to reinstall those stand-alone apps.)
This completes the download of Microsoft 365 to your device. To complete the installation and activation steps, follow the prompts in the following install and activation sections.
