Solution 1Recommended

Use Telephone Activation to View the Installation ID

The Installation ID is specifically generated and displayed when you opt to activate your Microsoft Office software via telephone instead of over the internet.

By default, Office 2010 attempts to activate over the internet, which bypasses the screen that displays your Installation ID. To see the ID, you must manually select the telephone activation option.

1
Launch an Office Application

Open any Office 2010 program on your new computer, such as Microsoft Word or Microsoft Excel.

2
Open the Activation Wizard

If the Activation Wizard doesn't open automatically upon launching the app, click on the 'File' tab in the top-left corner, select 'Help' from the left menu, and click on 'Activate Product Key'.

3
Select Telephone Activation

When prompted with activation methods, check the box that says 'I want to activate the software by telephone' and click 'Next'.

4
Locate the Installation ID

Look at Step 2 on the wizard screen. You will see a long string of numbers—this is your unique Installation ID required for telephone activation.

Telephone Activation Limitations: Because Office 2010 is unsupported, you may experience issues reaching an automated activation center. In this case, you will need to seek help from the Microsoft Q&A community.

Frequently Asked Questions

Why is the Installation ID not showing up for Office 2010?

This typically happens if the software is attempting to activate automatically over the internet. You must specifically select the 'activate by telephone' option in the Activation Wizard to force the system to display your Installation ID.

Can I still activate Office 2010 today?

Yes, you can theoretically still activate Office 2010 if you have a valid product key. However, because Microsoft ended support on October 13, 2020, they no longer provide technical support or customer service assistance if the activation fails.

What happens if I cannot activate Office 2010?

If Office 2010 remains unactivated, it will eventually enter Reduced Functionality Mode. In this mode, you will only be able to open and view documents, but you will not be able to edit them, save changes, or create new documents.
