If your Office product key doesn’t work, or has stopped working, you should contact the seller and request a refund. If you bought a product key separate from the software, it’s very possible the product key was stolen or otherwise fraudulently obtained, and subsequently blocked for use. Unfortunately, there are many dishonest sellers who offer stolen, abused, or otherwise unauthorized Microsoft product keys for sale. Sometimes these product keys are printed on counterfeit labels or cards with a download link to Microsoft software, and sometimes they’re distributed with software media that is unauthorized for resale, such as promotional media, original equipment manufacturer reinstallation media, or other Microsoft program-specific media.

Buy Office

If you're not able to get a refund from the original seller and you want to buy Office, select Buy Office below to compare prices and buy Office from the Microsoft Store.

0xC004F035 Invalid Volume License Key

The full text of this error message resembles the following:

Error: Invalid Volume License Key. In order to activate, you need to change your product key to a valid Multiple Activation Key (MAK) or Retail key. You must have a qualifying operating system license AND a Volume license Windows 7 upgrade license, or a full license for Windows 7 from a retail source. ANY OTHER INSTALLATION OF THIS SOFTWARE IS IN VIOLATION OF YOUR AGREEMENT AND APPLICABLE COPYRIGHT LAW.

Possible cause

Windows 7 Volume editions are licensed only for upgrade. Microsoft does not support installing a Volume operating system on a computer that does not have a qualifying operating system installed.

This error code indicates the following: “The Software Protection Service reported that the computer could not be activated with a Volume license product key...” The error text is correct, but it is ambiguous. This error indicates that the computer is missing a Windows marker in the BIOS. This marker appears on OEM systems to indicate computers that ship together with qualifying editions of Windows. The marker is required for KMS client activation.

Resolution

Install a qualifying version of a Microsoft operating system, and then activate by using an MAK.

0xC004F038 The count reported by your Key Management Service (KMS) is insufficient

The full text of this error message resembles the following:

The Software Protection Service reported that the computer could not be activated. The count reported by your Key Management Service (KMS) is insufficient. Please contact your system administrator.

Possible cause

The count on the KMS host is not high enough. For Windows Server, the KMS count must be greater than or equal to 5. For Windows (client), the KMS count must be greater than or equal to 25.

Resolution

Before you can use KMS to activate Windows, you must have more computers in the KMS pool. To obtain the current count on the KMS host, run Slmgr.vbs /dli.

0xC004F039 The Key Management Service (KMS) is not enabled

The full text of this error message resembles the following:

The Software Protection Service reported that the computer could not be activated. The Key Management Service (KMS) is not enabled.

Possible cause

KMS did not respond to the KMS request.

Resolution

Troubleshoot the network connection between the KMS host and the client. Make sure that TCP port 1688 (default) is not blocked by a firewall or is otherwise filtered.

0xC004F041 The Software Protection Service determined that the Key Management Server (KMS) is not activated

The full text of this error message resembles the following:

The Software Protection Service determined that the Key Management Server (KMS) is not activated. KMS needs to be activated.

Possible cause

The KMS host is not activated.

Resolution

Activate the KMS host by using either online or telephone activation.

0xC004F042 The Software Protection Service determined that the specified Key Management Service (KMS) cannot be used

Possible cause

This error occurs if the KMS client contacted a KMS host that could not activate the client software. This can be common in mixed environments that contain application-specific and operating system-specific KMS hosts, for example.

Resolution

Make sure that if you use specific KMS hosts to activate specific applications or operating systems, the KMS clients connect to the correct hosts.

0xC004F050 The Software Protection Service reported that the product key is invalid

Possible cause

This can be caused by a typo in the KMS key or by typing in a Beta key on a Released version of the operating system.

Resolution

Install the appropriate KMS key on the corresponding version of Windows. Check the spelling. If the key is being copied and pasted, make sure that em-dashes were not substituted for the hyphens in the key.

0xC004F051 The Software Protection Service reported that the product key is blocked

Possible cause

The activation server determined that Microsoft has blocked the product key.

Resolution

Obtain a new MAK or KMS key, install it on the system, and activate.

0xC004F064 The Software Protection Service reported that the non-genuine grace period expired

Possible cause

Windows Activation Tools (WAT) has determined that the system is not genuine.

Resolution

For assistance, contact the Microsoft Licensing Activation Centers.

0xC004F065 The Software Protection Service reported that the application is running within the valid non-genuine period

Possible cause

Windows Activation Tools has determined that the system is not genuine. The system will continue to run during the Non-Genuine grace period.

Resolution

Obtain and install a genuine product key, and activate the system during the grace period. Otherwise, the system will go into the Notifications state at the end of the grace period.

0xC004F06C The request timestamp is invalid

The full text of this error message resembles the following:

The Software Protection Service reported that the computer could not be activated. The Key Management Service (KMS) determined that the request timestamp is invalid.

Possible cause

The system time on the client computer is too different from the time on the KMS host. Time sync is important to system and network security for a variety of reasons.

Resolution

Fix this issue by changing the system time on the client to sync with the KMS host. We recommend that you use a Network Time Protocol (NTP) time source or Active Directory Domain Services for time synchronization. This issue uses UTP time and does not depend on Time Zone selection.

Windows Xp Activation Error

0x80070005 Access denied

The full text of this error message resembles the following:

Access denied. The requested action requires elevated privileges.

Possible cause

User Account Control (UAC) prohibits activation processes from running in a non-elevated Command Prompt window.

Resolution

Run slmgr.vbs from an elevated command prompt. To do this, on the Start menu, right-click cmd.exe, and then select Run as administrator.

0x8007232A DNS server failure

Possible cause

The system has network or DNS issues.

Resolution

Troubleshoot network and DNS.

0x8007232B DNS name does not exist

Possible cause

The KMS client cannot find KMS server resource records (SRV RRs) in DNS.

Resolution

Verify that a KMS host has been installed and DNS publishing is enabled (default). If DNS is unavailable, point the KMS client to the KMS host by using slmgr.vbs /skms <kms_host_name>.

If you do not have a KMS host, obtain and install an MAK. Then, activate the system.

For more information about troubleshooting such DNS-related issues, see Common troubleshooting procedures for KMS and DNS issues.

0x800706BA The RPC server is unavailable

Possible cause

Firewall settings are not configured on the KMS host, or DNS SRV records are stale.

Resolution

On the KMS host, make sure that a firewall exception is enabled for the Key Management Service (TCP port 1688).

Make sure that the DNS SRV records point to a valid KMS host.

Troubleshoot network connections.
