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 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 www.office.com and select Other install options, choose the language and version you want (64 or 32-bit), and then select Install. (See Install Visio or Install Project if you need to reinstall those stand-alone apps.)
