Welcome to the forums, Vern.
Someone did not pay attention when he started the download.
Look for this file ... setupeng.exe ... and double click on it to start the installation.
But, before you do this, be sure that there are no other antivirus programs installed as this will cause a conflict. Uninstalling other av programs though "Add/remove Programs" (or the Vista equivilent) is not enough. The appropriate removal tool for whatever other av program that might have been must be used.
If you have any other questions, please post again.
