Microsoft Office 365 Offline Installer

<Language ID="es-es" />

Warning: Be careful where you download Office ISOs. Torrent sites and third-party download aggregators often bundle malware, rootkits, or "cracks" that compromise your security. You should only obtain the offline installer directly from Microsoft.

Here is the official, step-by-step method to generate your own legitimate ISO file.

You now have a portable offline installer. microsoft office 365 offline installer

This is the core of the offline installer. The setup.exe reads an XML file that tells it what version of Office to download and where to put it.

Open Notepad (as Administrator). Paste the following code: <Language ID="es-es" />

<Configuration>
  <Add OfficeClientEdition="64" Channel="MonthlyEnterprise">
    <Product ID="O365ProPlusRetail">
      <Language ID="en-us" />
    </Product>
  </Add>
  <Property Name="SharedComputerLicensing" Value="0" />
  <Property Name="PinIconsToTaskbar" Value="TRUE" />
  <Property Name="SCLCacheOverride" Value="0" />
  <Updates Enabled="TRUE" />
  <RemoveMSI />
  <Display Level="None" AcceptEULA="TRUE" />
</Configuration>

What this means:

Save this file as config-download.xml inside C:\ODT. Warning: Be careful where you download Office ISOs

Use a text editor to create config-offline.xml. Example (English 64-bit, current channel, Word, Excel, PowerPoint, Outlook):

<Configuration>
  <Add OfficeClientEdition="64" Channel="Current">
    <Product ID="O365ProPlusRetail">
      <Language ID="en-us" />
      <ExcludeApp ID="Publisher" />
      <ExcludeApp ID="OneNote" />
    </Product>
  </Add>
</Configuration>

For Volume License versions (e.g., O365ProPlusVL), adjust the Product ID accordingly.

If you frequently wipe and reload computers (common in schools, testing labs, or PC repair shops), the online installer becomes a bottleneck.
