install Analytics Processor

Hi,

I have my controller installed on one machine, the eum on the same machine.. BUT  I need the analytics processor in order the EUM server works.... I follow this link:https://docs.appdynamics.com/display/PRO40/Install+the+Controller+and+Clustered+Analytics+Processor, the thing is:

* Where do I get the Analytics processor?....

* Do i have to download the Zookepper from: http://www.eu.apache.org/dist/zookeeper/zookeeper-3.4.7/ ?

Please, can someone clarify this, where do I get the Analytics Processor?.

Regards,

Michael.
