Error 0x80096004: Unable to Verify the Digital Signature of the Office Package

This error occurs in: Office 2019, Office 2021, Office 2024.

Cause

Symptoms

• During activation, the message appears: "Unable to verify the digital signature of the Office package"
• Error code: 0x80096004
• English version: "The digital signature for the package could not be verified"

Step-by-Step Solution

Download the Office installation package directly from the official Microsoft website (office.com or microsoft.com). Do not use files from unofficial sources.

Solution for Office

1. Open any Office application (Word, Excel)
2. File → Account → Change product key
3. Enter the key from KluczeSoft
4. Click Activate

Alternatively, through the command line:

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

Verification

Still Not Working?

If the above steps did not help:

1. Check the date and time — they must be correct (an incorrect date can block activation)
2. Temporarily disable antivirus and try again
3. Check your internet connection — online activation requires a connection to Microsoft servers
