I am trying to deploy a .cab file consisting of an ocx and some dll's over the internet. My html page's code successfully downloads and extracts the .cab to the local machine. However, when it is done, the message box "You will need to reboot your system for the new settings to take effect" appears. But the PC does not need to be rebooted for the ocx to work. We have other .cab files that get downloaded without getting that message. What actions cause that message to be displayed? Is there a way to prevent that message from being displayed? Thanks!
