Verify that signcode.exe is located in the Windows directory. If this file already exists, verify that Microsoft's digital signing tool (the ActiveX SDK), now known as Authenticode, exists on the development computer. Download the Authenticode tool for Internet Explorer 4.0
or Internet Explorer 5.0
. In addition, you must also have a platform-specific Code Signing ID from the certificate authority. For more information on code signing, please refer to issuers' website. For more information on Authenticode, please refer to Microsoft's Web site
