You did not tell us which version you are using. One solution may be that you need to go to http://www.uftree.com/UFT/Nav/ufttech.htmlhttp://www.uftree.com/UFT/Nav/ufttech.html and download the Admin.zip file which is under "Configuring UFT to work with Microsoft Internet Explorer 5.0" and follow the instructions there to install the file.
You may also want to download UFT version 2.8 if you are using an older version. It is on the same URL but is under the heading Ultimate Family Tree 2.8 Maintenance Release (PC only).
If you are using version 3.0 you may want to download version 3.1. It is at the same URL under the heading UFT 3.10 Update.
