Office 365 for ARM64

I am currently experiencing serious problems with Office 365 on an HP Elitebook ultra G1q notebook, Snapdragon® X Elite X1E-78-100 processor, Windows 11 Pro operating system. Outlook does not refresh...

Try this to force Office 365 ARM64 installation:

 

  1. Use the Office Deployment Tool

Download the Office Deployment Tool and create a custom configuration file to explicitly target ARM64:

 

<Configuration>
  <Add OfficeClientEdition="64" Channel="Current">
    <Product ID="O365ProPlusRetail">
      <Language ID="en-us" />
    </Product>
  </Add>
  <Property Name="ARM64" Value="TRUE" />
  <Display Level="None" AcceptEULA="TRUE" />
</Configuration>

Run the installer using:

setup.exe /configure configuration.xml

This forces the ARM64 version to install, bypassing auto-detection quirks.

 

  1. Check Installed Architecture

After installation, verify the architecture:

  • Open Word or Outlook
  • Go to File > Account > About
  • Look for “ARM64” in the version string. If it says “x86” or “x64,” it’s not the correct build.
