Solution 1Recommended

Activate Office from a New Windows User Profile

Creating a fresh user profile can bypass corrupted local account settings that may trigger activation errors.

Sometimes, the local Windows user profile can become corrupted or have conflicting registry settings that interfere with the Microsoft Office activation process. Testing activation from a clean user profile can isolate and resolve the issue.

Open Windows Settings

Press the Windows key + I on your keyboard to open Settings, then navigate to 'Accounts'.

Add a New User

Select 'Family & other users' from the left pane, and click 'Add someone else to this PC' under the Other users section.

Log In and Activate

Log out of your current session, log into the newly created Windows user profile, open any Office application like Word, and attempt the activation process again.

Protect Your Data: If you need to seek further help on public forums, ensure your product key, CID code, and personal email address are fully redacted from any screenshots you share.

Solution 2

Verify Your Office Edition and Product Information

Confirming your exact Office edition helps determine if the CID request is valid for your specific license type.
