Foxit PDF Reader installation error, really disgusting.

I have installed Windows 8.1 on my system and I tried to install Foxit PDF Reader. When I run the setup, it allows me to go through a series of steps but when the installation starts, a dialog box appears, 'Do you want to exit the setup?' If I click on NO then the installation continues for a second or two and I again get the same error. How can I fix this?
