I have tried this on a number of systems and I cannot get any of the add-ons (for searches) to install from Microsoft's Internet Explorer Gallery. The "Add to Internet Explorer" button does nothing. I am thinking this is a Java problem. In addition, historically if I go to
https://www.google.com a little tool bar will pop up asking me if I want to install google search as my primary engine. This too has stopped. Any suggestions?
The search engine is here:

It will not even work with IE as an administrator
Are you using the procedure described here under "To add new Search providers"?

If you did and you still have the problem:
Repair IE FixIt. I suspect this is an add-on problem.

Reset IE

And if still no help:
Uninstall/reinstall IE

Sometime you can fix IE by using Control Panel|Programs and Features|"Turn Windows Features on or off" . Uncheck IE|OK When finished you have to reboot. Then go back to "Turn Windows Features on or off" and check the IE box. When finished you have to reboot again.
