No serial number for evaluation version?

Hi,

I downloaded an evaluation version of Intel® Visual Fortran Composer XE for Windows* 2013 SP1. But I didn't get a serial number or license file. When I installing it, I have only one choice to select "Evaluate this product" at the Activation tab. After installing the software, it doesn't work! Other ways all require a serial number or license file. What should I do?
