python
import subprocess

def activate_office(product_key):
try:
# Run the Office activation command using the provided product key
activation_result = subprocess.run(['cscript', '//Nologo', 'ospp.vbs', '/inpkey:' + product_key])

if activation_result.returncode == 0:
print("Office activation successful!")
else:
print("Office activation failed. Error code:", activation_result.returncode)

except Exception as e:
print("An error occurred during Office activation:", str(e))

# Example usage:
product_key = "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX" # Replace with your own product key
activate_office(product_key)

In the sample code above, we use the `subprocess` module in Python to run a command-line script (`ospp.vbs`) responsible for Office activation. The `activate_office` function takes a `product_key` as input and attempts to activate Office using that key. It then checks the return code to determine if the activation was successful or not.

Please note that this code assumes you have the necessary permissions to execute the `ospp.vbs` script and that the script is located in the appropriate directory. Additionally, it is essential to have a valid product key for Office activation.

Remember, the provided code is a general approach and may not directly address the specific error code you mentioned. It is always recommended to consult official Microsoft documentation or support channels for specific error codes and their resolutions.
