Architecture

32-bit of Office is the default choice. Computers running 64-bit versions of Windows generally have more resources such as processing power and memory, than their 32-bit predecessors. Also, 64-bit applications can access more memory than 32-bit applications. Therefore, if your scenarios include large files and/or working with large data sets and your computer is running 64-bit version of Windows, 64-bit is the right choice when:

• You’re working with large data sets, like enterprise-scale Excel workbooks with complex calculations, many pivot tables, data connections to external databases, Power Pivot, 3D Map, Power View, or Get & Transform. The 64-bit version of Microsoft 365 may perform better in these cases.
• You’re working with extremely large pictures, videos, or animations in PowerPoint. The 64-bit version of Microsoft 365 may be better suited to handle these complex slide decks.
• You’re working with files over 2 GB in Project, especially if the project has many sub-projects.
• You’re developing in-house Microsoft 365 solutions like add-ins or document-level customization. Using the 64-bit version of Microsoft 365 lets you deliver a 64-bit version of those solutions as well as a 32-bit version.
• You’re working with the Large Number data type in Access, and while this data type is supported by 32-bit Access, you may see unexpected results when executing code or expressions that use native 32-bit VBA libraries. 64-bit VBA provides the LongLong data type which fully supports large numbers.

For more information please refer to Choose between the 64-bit or 32-bit version of Office.

Tip

If you are using ARM64-based Windows, you can select ARM64 (64-bit compatible) for better performance and compatibility.

Update channel

In most cases, Current Channel is the default channel. The table below lists the differences between the channels:

Update Channel	Channel ID	Release frequency	Feature updates
Current Channel	Current	At least once a month, but on no set schedule	Same as release frequency
Semi-Annual Enterprise Channel	SemiAnnual	Once a month, on the second Tuesday of the month	Twice a year (in January and July)
Monthly Enterprise Channel	MonthlyEnterprise	Once a month, on the second Tuesday of the month	Same as release frequency
Office 2019 Perpetual Enterprise	PerpetualVL2019	Once a month, on the second Tuesday of the month	None
Office 2021 Perpetual Enterprise	PerpetualVL2021	Once a month, on the second Tuesday of the month	None

The Perpetual Enterprise channel is a dedicated channel for Office 2019/2021 volume products.

All of the channels listed in the table are stable channels and can be used on a daily basis.

Each channel releases security updates (if needed) on the second Tuesday of each month, which is scheduled.

For more information please refer to Overview of update channels for Microsoft 365 Apps.

Modules

Office Deployment Tool

Office Deployment Tool is an official Microsoft tool that provides complete support for deploying Office.

Office Tool Plus

We recommend prioritizing the use of the Office Deployment Tool, and should only choose Office Tool Plus if there are issues with the Office Deployment Tool that cannot be resolved, or if there are special needs.

Products

If you have a genuine Office license, install your own purchased version of Office.

If you want to use KMS or MAK to activate Office, install volume license products, such as Office 2019 Volume License or Office 2021 Volume License.

Languages

You can add one or more languages that you want. The first full type of language in the list determines the Shell UI culture, including shortcuts, right-click context menus, and tooltips. If you decide to change the Shell UI language after an initial installation, you have to reinstall Office.

If you do not add a language, Office will automatically match the system language, or fall back to the language specified in Advanced settings - Installation settings - Fallback language if the system language cannot be matched.

If you check Deploy proofing tools only, the language will be installed as proofing tools without display language.

Language types

Type	Description
Full	Includes display language and proofing tools.
Partial	Includes display language for some Office applications and includes proofing tools.
Partial without proofing tools	Includes display language for some Office applications but does not include proofing tools.
Proofing tools	Only include spell checker.

Installation files

When you download Office from Office Tool Plus, Office Tool Plus will automatically detected the Office installation and displays it here.

Tips

Office installation files should show version number and languages information in its entirety without errors. If the installation files does not contain language, or contains only proofing tool, the installation will still require an Internet connection, otherwise the installation will fail.

If you have local installations, you can click Select file and then specify any of the CAB files in the Office installation.

The Office ISO image should be mounted or extracted before selecting the CAB file contained within it.

If the installation shows an error, you should check and fix the problems before deploying.
