  • Windows 8
  • Windows 7
  • Windows Vista
  • Windows Server 2012
  • Windows Server 2008 R2
  • Windows Server 2008
Additionally, you may experience one or more of the following symptoms:
  • Activation fails and generates error code 0x8004FE33.
  • The following Error events are recorded in the Application log:
    Log Name: Application
    Source: Software Licensing Service
    Event ID: 8198
    Level: Error Description: License Activation (SLUI.exe) failed with the following error code: 0x80004005
    Log Name: Application

    Event ID: 1008
    Level: Error Description: Acquisition of Secure Processor Certificate failed. Status Code=hr=0x8004FE33
  • Activation fails, and you are not prompted for credentials.

Cause

These issues may occur when you connect to the Internet through a proxy server on which Basic authentication is enabled.

If the proxy server is configured for Basic authentication, the server requires that you type a username and a password. However, the activation user interface does not let you enter these credentials. Therefore, the Basic authentication fails, and activation fails.

Workaround

General users

Method 1: Use the telephone to activate Windows

Start the Windows Activation Wizard to use the automated telephone system and activate Windows. To start the wizard, click Start, click Run, type SLUI 04, and then click OK.

If you are running Windows 8, follow these steps:
  1. Swipe in from the right edge of the screen, and then tap Search. Or, if you are using a mouse, point to the lower-right corner of the screen, and then click Search.
  2. Type SLUI 04, and then tap or click the displayed icon to open the wizard.

Method 1: Configure the proxy server to disable Basic authentication

For information about how to perform this method, see the documentation that is included with the proxy software.

Method 2: Configure your proxy server to exclude the URLs for the certificate revocation lists (CRLs) from the requirement for Basic authentication

To do this, configure the following list of CRLs to be unauthenticated on the proxy server:
  • http://go.microsoft.com/
  • https://sls.microsoft.com/
  • https://sls.microsoft.com:443
  • http://crl.microsoft.com/pki/crl/products/MicrosoftRootAuthority.crl
  • http://crl.microsoft.com/pki/crl/products/MicrosoftProductSecureCommunications.crl
  • http://www.microsoft.com/pki/crl/products/MicrosoftProductSecureCommunications.crl
  • http://crl.microsoft.com/pki/crl/products/MicrosoftProductSecureServer.crl
  • http://www.microsoft.com/pki/crl/products/MicrosoftProductSecureServer.crl
  • https://activation.sls.microsoft.com
For information about how to perform this method, see the documentation that is included with the proxy software.
