[Dx4win] Install 2.24

[N7KA at comcast.net]

Downloaded and saved the 114.1 WINDOWS Installer Package.
The file says tqsl-114-1, Windows Installer Package, 170kB. (does not indicate it is a zip file)
I double click on the tqsl-114-1 icon then click RUN and I get a message that says "This instalation package could not be opened.  Contact the applicaion vendor to verify tat this is a valid Windows Installer package.  OK" 

What am I doing wrong?
