My company ships a signed ActiveX control. On some machines running Windows
2k3 and IE 6, when the ActiveX control is downloaded, an error dialog appears
titled "Security Alert - Driver Installation", with the message "The driver
software you are installing has not been properly signed...".

This seems odd because the .CAB file does not contain drivers, so it would
seem that IE is somehow using the wrong signature verification method. I have
verified via "signtool verify /pa /v" that the .CAB file is correctly signed
with a valid certificate. So why doesn't IE agree?

Any thoughts or pointers appreciated.
