There are two versions of this update: one for the UFT 3.0 which was distributed via the Internet, and another for the version of UFT 3.0 which was distributed on CD. Both files are about 500 Kbytes in size. After clicking on the download link, you should be presented with a window where you can select the directory to receive the download of the file. You can place the update file in any directory. When you run the update, it will search your hard drive(s) for the current version of UFT. If you select and try the wrong one, it will do no harm - it simply will not work.
