How to Download and Install Office LTSC Standard 2021




To download and install Office LTSC Standard 2021 offline installer, you need to use the Office Deployment Tool (ODT), which is a free download from the Microsoft Download Center. The ODT allows you to customize your installation and deployment options, such as which apps and languages to install, where to install from, and how to activate the product.


Download the Office Deployment Tool




The first step is to download the ODT from the . After you download it, double-click on the officedeploymenttool executable (.exe) file to extract the ODT files. You should have two files: setup.exe and configuration.xml.


Create the configuration.xml file




The next step is to create or edit the configuration.xml file, which contains the settings for your installation. You can use any text editor to create or modify the configuration.xml file that comes with the ODT. You can also use the , which is a web-based tool that helps you create and edit the configuration.xml file.


The configuration.xml file contains several elements and attributes that specify your installation options. For example, you can use the Add element to specify which Office products, languages, and architectures to install. You can use the SourcePath attribute to specify the location of the installation files. You can use the Product ID attribute to specify the edition of Office LTSC Standard 2021 that you want to install.


Here is an example of a configuration.xml file that installs Office LTSC Standard 2021 for 64-bit devices in English from a local folder named Office:



<Configuration> <Add SourcePath="C:\Office" OfficeClientEdition="64" Channel="PerpetualVL2021"> <Product ID="Standard2021Volume"> <Language ID="en-us" /> </Product> </Add> </Configuration>


Download the Office LTSC Standard 2021 installation files




The next step is to download the Office LTSC Standard 2021 installation files from Microsoft's servers to your local folder. To do this, you need to run the setup.exe file with the /download option and specify the configuration.xml file as a parameter. For example, if your configuration.xml file is in the same folder as the setup.exe file, you can open a command prompt window and type the following command:



setup.exe /download configuration.xml


This will download the installation files to the folder that you specified in the SourcePath attribute of your configuration.xml file. Depending on your internet speed and the size of the files, this may take some time.


Install Office LTSC Standard 2021 by using the Office Deployment Tool




The final step is to install Office LTSC Standard 2021 by using the ODT. To do this, you need to run the setup.exe file with the /configure option and specify the configuration.xml file as a parameter. For example, if your configuration.xml file is in the same folder as the setup.exe file, you can open a command prompt window and type the following command:



setup.exe /configure configuration.xml


This will start the installation process of Office LTSC Standard 2021 according to your configuration settings. You may see some prompts or messages during the installation, but you do not need to interact with them. The installation may take several minutes to complete.


How to Activate Office LTSC Standard 2021




After you install Office LTSC Standard 2021, you need to activate it by using a valid product key or a volume activation method. There are two ways to activate Office LTSC Standard 2021: Key Management Service (KMS) or Multiple Activation (MAK).


Use Key Management Service (KMS) to activate Office LTSC Standard 2021




KMS is a service that allows organizations to activate multiple devices by using a local server that hosts a KMS host key. To use KMS to activate Office LTSC Standard 2021, you need to have a KMS host key for Office LTSC Standard 2021 and configure your KMS host server accordingly. You also need to ensure that your devices can connect to your KMS host server over the network.


To activate Office LTSC Standard 2021 by using KMS, you need to run the ospp.vbs script with the /act option on each device that has Office LTSC Standard 2021 installed. The ospp.vbs script is located in the %ProgramFiles%\Microsoft Office\Office16 folder. For example, you can open a command prompt window as an administrator and type the following command:



cscript ospp.vbs /act


This will attempt to activate Office LTSC Standard 2
