To use AFC Setup Autoinstall, add the following tag to your HTML page:
The CLASSID parameter specifies the GUID for AFC Setup; this is a unique identifier in the registry which is checked when the page loads.
CODEBASE is the name of the program to run, followed by a # and a version number. This version number is compared to the one stored in the registry with the GUID. If the version on the page is newer, the program is downloaded and run automatically. If the page's version is older, nothing happens. There is no download unless it is necessary.
The WIDTH and HEIGHT tags are set to 0 because we don't want any space on the page allocated for this control.
