Install Office LTSC or Volume editions with the Office Deployment Tool

When this applies

Office volume editions — Professional Plus, Standard, LTSC and MAK keys — are not installed from office.com/setup. You install them from an ISO or with the Office Deployment Tool (ODT).

What you need

• Your product key (order confirmation email / Lizensa dashboard)
• The Office ISO from your order page, or the Office Deployment Tool
• A Windows PC with administrator rights

Option A — Install from the ISO (recommended)

1. Download your ISO from the link in your order email (see Download and install your ISO from Lizensa storage).
2. Double-click the ISO to mount it — Windows 10 and 11 mount ISOs natively.
3. Run setup.exe from the mounted drive and follow the wizard.

Option B — Install with the Office Deployment Tool

1. Download the ODT and extract it to a folder.
2. Create a configuration.xml for the volume product you bought, for example:

<Configuration>
  <Add OfficeClientEdition="64">
    <Product ID="ProPlus2021Volume" PIDKEY="XXXXX-XXXXX-XXXXX-XXXXX-XXXXX">
      <Language ID="MatchOS" />
    </Product>
  </Add>
  <Display Level="Full" AcceptEULA="TRUE" />
</Configuration>

3. From an elevated command prompt run:

setup.exe /configure configuration.xml

Activate

• MAK key: open any Office app and enter the key when prompted, or activate from the command line:

cd "C:\Program Files\Microsoft Office\Office16"
cscript ospp.vbs /inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
cscript ospp.vbs /act

• If online activation is refused for a volume edition, use phone activation: run slui 4 or pick Activate by phone in the Office activation wizard.
