Symptoms
Windows activation or validation fails when you try to activate Windows operating systems over the Internet.
Additionally, you may receive one or more of the following errors:
-
Error code: 0x80004005 Description: License Activation (SLUI.exe) failed.
-
Error code: 0x8004FE33 Description: Acquisition of Secure Processor Certificate failed.
-
The activation failure does not prompt you for credentials.
These problems may occur when you connect to the Internet through a proxy server on which Basic authentication is enabled.
Note: 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.
If you experience other errors than those mentioned above when you try to activate Windows, go to the following Windows websites for additional troubleshooting information:
