Internet Explorer Add-on Installer

I just tried to access a National Weather Service site to view radar images

(because of local weather warnings).

http://radar.weather.gov/radar.php?rid=gsp...ct=NCR&loop=yes

When trying to view the Composite Reflectivity Loop (enhanced version), the

Information Bar popped up telling me that IE had stopped the site from

installing an Active-X control. When I clicked to install the control (I

certainly trust _this_ site), the User Account Control came up and asked

for administrator permission to install the control. I clicked continue

and then got back the message that "Windows has blocked the software

because it cannot verify the publisher." There was no way I could

continue.

How do I override this flakey protection that completely prevents me from

viewing the time-loop images?
