java.lang.NoClassDefFoundError: Files\Apache on launching ActiveMQ

I've downloaded Apache ActiveMQ 5.9.0 and I'm trying to launch it. Following, the command I've typed and the output:

c:\Program Files\Apache Software Foundation\apache-activemq-5.9.0>bin\activemq
java.lang.NoClassDefFoundError: Files\Apache
Caused by: java.lang.ClassNotFoundException: Files\Apache
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: Files\Apache.  Program will exit.
Exception in thread "main"

I'm following the official guide on Running an ActiveMQ Broker and I'm working under Windows 7.

Any suggestions?

Thank you in advance.

I've found a solution. The issue is related to the white spaces in the path; indeed, Files\Apache in the exception message refers to a part of the path c:\Program Files\Apache Software Foundation\apache-activemq-5.9.0>bin\activemq. I've quickly solved it moving the ActiveMQ folder to a "whitespace-free" path and now it works.
