How do I re-install Acrobat X Standard?

My computer had to be re-installed with Windows. Now I'm in the process of putting all my programs back on. However, when I try to install Adobe Acrobat X Standard, I continually get the following message: "This application cannot be installed on this operating system. Setup will now terminate. Please refer to the minimum requirements at http://www.adobe.com/go/acrobat_system_reqs."

I should have the minimum system reqs since I had them before. How do I get Acrobat to install?
