Symfony - Problems installing in Windows 8

I'm trying to install Symfony in Windows 8, but I get the message from Windows that "This application can not be run on your PC". This occurs when, through the CLI, I try the command symfony generate:project symfony_project inside the C: \ wamp \ www \ symfony_project

The idea is to install in WAMP, and I'm following the tutorials of the links:

• link
• link (in this case, I tried to use Composer, but the message is the same).

Would it be a version problem? Or is there another way to install?
