I purchased Microsoft Office Home & Business 2021 bundled with my HP Victus laptop. There is no separate product key. Office worked fine for 3 years with no issues. The problem just started a few days ago without any changes made on my end. Now Office is showing read-only mode and says license is not installed. Error code: 0xC004F017. Please help me reactivate it.

1

Open Word.

At the top right of Word, log out of Office.

Restart (not shut down) your PC, then log back into Office, is your subscription then recognised correctly.

2

If not, log into your Microsoft account on this link, is your Office licence listed correctly there?

    Error code 0xC004F017 indicates that the Office license is not installed. When this happens, Office goes into read-only (Unlicensed Product) mode and most features are disabled.

    For a bundled Office Home & Business 2021 (no separate key), activation is tied to the Microsoft account and device. The supported remediation from the provided information is to repair the activation state so that the license is correctly installed again.

    Follow these steps in order:

    1. Confirm the correct Microsoft account
      • Open any Office app (for example, Word).
      • Go to File > Account.
      • Under User Information, check which account is signed in.
      • Make sure this is the same Microsoft account that was originally used to activate Office on this HP Victus. If it is not, sign out and sign in with the original account.
    2. Run Office activation repair (to reinstall the license)
      • Because 0xC004F017 maps to “license is not installed,” use the Office repair mechanism that fixes activation process issues and reinstalls missing or damaged license components.
      • Close all Office apps.
      • Use the Office Repair tool as documented for activation issues so that it can repair the Software Licensing Service state and reinstall the missing license. This specifically addresses errors like 0xC004F010 (invalid key) and related activation-process errors where the license is missing or corrupted.
    3. Retry activation
      • After repair completes, open Word or Excel.
      • If prompted, sign in with the same Microsoft account confirmed in step 1.
      • Check File > Account to verify that the product no longer shows Unlicensed Product and that the subscription or perpetual license is listed as activated.
    4. If activation still fails
      • Because this is an OEM-bundled perpetual license and the error indicates a missing license, and if repair plus correct account sign-in do not restore activation, contact Microsoft Support with the device purchase details so they can check and restore the entitlement associated with the device and account.
