And where you are clicking these files...I think most of us are assuming you are looking at the files on your computer, not the website. On windows press the Windows logo key + E to open File Explorer. In File Explorer click on the downloads folder. In downloads you should see the two files you downloaded. Left double-click on "Install Poser 11.exe" and run that install. When that is done, left double-click on "PoserSupport.exe" to install that.
