How to install Office LTSC installation files not found in VLSC

Office files can be downloaded separately.

Follow these steps to download and install your Office LTSC, Visio LTSC, or Project 2021 software or application.

1. In Microsoft Edge, browse to Office Deployment Tool, and then select Download.

   Note

   The file will automatically be saved to the Downloads folder on your device. Office LTSC 2021 requires version 16.0.14326.20404 or a later version of the Office Deployment Tool. This version was released on September 17, 2021.

2. Select the Open file link under the file name.

   

3. A pop-up window will display the Microsoft Software License Terms. Select the check box to accept the terms, and then select Continue.

   Note

   If you are prompted to select a location that you want the files saved to, select the folder that you created.

   

4. When you are prompted to select a folder to store the extracted files in, select Desktop > Make New Folder > OK.

5. If you have purchased Office LTSC Professional Plus 2021, Visio LTSC Professional 2021, and Project Professional 2021, you can use the sample configuration file (configuration-Office2021Enterprise.xml) that's included with the Office Deployment Tool to install your products. In this case, you can skip to Step 22 in these instructions. If you have purchased only one of these products, go to the next step to use the Office Customization Tool.

7. Under Create a new configuration, select Create to open the Office Customization Tool.

   The following steps describe the simplest method to create a configuration file. For more information about the various configuration options, see Configuration options for the Office Deployment Tool.
