Software installation problems

I am trying to install from an installer application. ( Installer Vise Mind Visiion) When I unstuff the program I get a message that says

" No installation was necessary. The files to be installed are already on your disk, or are not needed for your hardware setup. If you are finished click quit to leave the installer program. When I go back to look at the files there is nothing there."

When I look at get info on the installer it shows that there is 18mgs of information in the installer program. When it unstuffs it shows that it is unstuffing 59 items.

Can anyone explain why I cannot find the program after performing the install?
