Office LTSC 2024 (32-bit) on Windows 11 VDI - "Non-Genuine" Message Despite Successful KMS Activation

Hi everyone,

I'm encountering an issue with Office LTSC Standard 2024 (32-bit) on a Windows 11 23H2 VDI environment. Despite what appears to be a successful KMS activation, a "non-genuine product" message is displayed when I launch applications like Excel.

Here's a summary of my setup and what I've tried:

Software: Windows 11 23H2 VDI and Office LTSC Standard 2024 32-bit.

License: I'm using a KMS license key obtained from VLSC (Volume Licensing Service Center).

KMS Server: The key has been successfully registered on our KMS server.

License Status Check: Using OSPP.VBS, the LICENSE STATUS is shown as ---LICENSED---. The REMAINING GRACE period is also regularly refreshed, suggesting the license is active.

DNS: We have a properly configured DNS server with the necessary SRV records pointing to our KMS host.

The activation seems to be working, yet the "non-genuine" message persists. Interestingly, the 64-bit version of Office activates without any issues and the message doesn't appear. The problem is specific to the 32-bit installation.

I came across some information online suggesting a registry modification to specify the KMS server address: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform and adding the KeyManagementServiceName key. However, I haven't found any official Microsoft documentation confirming this as a standard procedure for this specific scenario.

Could this be a valid solution, or is there another official or recommended method to resolve this?

Any insights or solutions would be greatly appreciated. Thanks in advance!

    Hi @mako
    Thank you for posting your question in the Microsoft Q&A forum.

    Let’s confirm a few things as below:

    Office Edition: LTSC Standard 2024 (32-bit)

    Activation: KMS activation completed successfully (OSPP shows LICENSED)

    Issue: “Non-Genuine” message still appears when opening apps like Excel.

    This usually happens if:

    • There are leftover Retail or older Office components.
    • Office is not pointing to the correct KMS host.
    • The wrong product key (GVLK) is installed.

    The HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OfficeSoftwareProtectionPlatform registry key is associated with the Office Software Protection Platform (OSPP), a service used by Microsoft Office to manage licensing, activation, and validation of Office products. This service ensures that the installed Office software is genuine and properly licensed.

    For reference: Activate volume licensed versions of Office by using KMS
    Beside, for further assistance, Could you please provide detail below:

    1. Run this command from C:\Program Files (x86)\Microsoft Office\Office16: cscript ospp.vbs /dstatusall
      • Does it show Standard2024Volume and PerpetualVL2024 channel?
      • Are there any other product keys (Retail or older Office) listed?
    2. Is your KMS host updated with the Office LTSC 2024 Volume License Pack?

    I also suggest some steps you could try (on one affected VDI)

    Reset and reconfigure KMS settings for Office:

    cscript ospp.vbs /inpkey:V28N4-JG22K-W66P8-VTMGK-H6HGR
cscript ospp.vbs /sethst:<KMS_FQDN>
cscript ospp.vbs /setprt:1688
cscript ospp.vbs /act

    (This uses the official GVLK for Office LTSC Standard 2024.)

    Remove extra keys if /dstatusall shows multiple products:

    cscript ospp.vbs /unpkey:<Last5Chars>

    Verify DNS SRV record for _vlmcs._tcp points to your KMS host.

    If the banner still appears, the next step is a clean redeployment of Office LTSC 2024 (32-bit) using the Office Deployment Tool with the PerpetualVL2024 channel to ensure no mixed components remain
