If you want to install Microsoft office for business, you can use the Office 2016 Offline Installer.

If you have an Office 365 for business product you can use the Office 2016 Deployment Tool to download and install Office 365 offline.

The tool is designed for enterprise environments and runs from the command line, so the steps are more complicated–but they’ll work for installation on a single device.

 

Download and install the Office 2016 Deployment Tool:

Create a folder on your hard drive and name it ODT. 

 

Download the Office 2016 Deployment Tool from the Microsoft Download Center.

Select Save As and save it to your downloads folder.

 

In your downloads folder, double-click the Office setup 2016 Deployment Tool exe file to install it.

 

If you see the User Account Control prompt that says, Do you want to allow this app to make changes to your device?, click Yes.

 

Accept the Microsoft Software License Terms, and then click Continue.

 

In the Browse for Folder dialog, select the ODT folder you created in earlier, and then click OK.

 

Download and Install Office:

If you have an Office 365 Business or Office 365 Business Premium plan, you need to download the Office Business version. For all other plans, download the Office 365 ProPlus version.
