Livecycle Server Install

Hi,

I want to install only livecycle Form Server trial version.
But I can't find it's download link.

Therefore I downloaded livecycle ES(WebSphere_EFGJ_DVD.zip) and I try to install livecycle server only from the package.
But all component installed When I run install Livecycle ES.

Is there a way to install only livecycle Form Server?

thanks.
