MS Access Runtime - FULL download

I currently have Office 2021 LTSC Std Edition (click-to-run). I'd like to obtain MS Access Runtime 365 for the purpose of viewing DB content, I don't need to create or update anything.

When I download the latest Runtime version it's not letting me have the full installation. It's the usual thing were it's an initial installer that wants to complete the install process by pulling the remaining install files from the Microsoft site.

Working in an air-gapped network prohibits me from using this install method. Where can I obtain the FULL installation?

Thanks!

Hi Mr Down

Just a quick note: if you install Access 365 Runtime on a machine that already has an existing Office Click‑to‑Run installation, the Runtime version installed will automatically match the version of Office currently on that device. Reference: Download and install Microsoft 365 Access Runtime

In air‑gapped environments where Internet access is restricted, you may consider downloading the full Access Runtime binaries in advance on a machine that has Internet connectivity by using the Office Deployment Tool

This is a command‑line utility that allows you to download and deploy Microsoft 365 Apps locally to client computers, while giving you control over which specific products are installed.

You may try running the following command on an Internet‑connected machine: setup.exe /download configuration.xml

With the configuration:

<Configuration>
  <Add OfficeClientEdition="64" Channel="PerpetualVL2021">
    <Product ID="AccessRuntimeRetail">
      <Language ID="en-us" />
    </Product>
  </Add>
  <Display Level="None" AcceptEULA="TRUE" />
</Configuration>

Once the download is completed, you can:

Save the downloaded installation files locally (e.g. USB drive / secure transfer)

Move the entire folder into the air‑gapped network

Then perform the installation offline by running: setup.exe /configure configuration.xml

    Using the xml configuration you supplied above, I performed the download.

    I subsequently transferred the install files to a standalone PC that already had Office 2021 LTSC installed. I then installed Access Runtime and successfully opened a database.

    Microsoft Access Runtime 365 is not distributed as a complete standalone offline installer. Instead, Microsoft provides it through a Click-to-Run (C2R) deployment model, where the initial download is only a small bootstrap file that retrieves the remaining installation components from Microsoft’s servers during setup. Due to this design, it is not possible to directly obtain a single “full installer” executable for use in an air-gapped environment.

    In addition, when Office 2021 LTSC (Click-to-Run) is already installed on a system, Microsoft enforces version alignment across Office products. As a result, installing Access Runtime 365 is not supported in this scenario. The system will instead use the equivalent Access Runtime version that matches Office 2021 LTSC, which is Access Runtime 2021.

    For environments without internet access, such as air-gapped networks, Microsoft provides an alternative deployment method using the Office Deployment Tool (ODT). This tool allows administrators to download all required installation files in advance and then perform an offline installation.

    The process involves creating a configuration XML file specifying the desired product (Access Runtime 2021), downloading the full installation source on a machine with internet access, and then transferring those files to the isolated environment. The installation can then be completed offline using the downloaded files.

    In conclusion, a fully packaged offline installer for Access Runtime 365 is not available. The recommended and officially supported approach for offline installation is to use the Office Deployment Tool to download and deploy Access Runtime 2021, which is fully compatible with an existing Office 2021 LTSC installation
