The JBoss Tools Fuse isn't listed on Summary screen though I have checked it on Features screen.

There is summary I got:

Installation path:
    /home/lvalach/JBDS/test4
Java VM path:
    default
Components to install:
    Red Hat JBoss Developer Studio 11.0.0.AM1
Disk Space:
    Available Disk Space: 65.28 GB 
    Required Disk Space: 753.83 MB

I think that problem is here [1]. Fuse is no longer in integration-stack.fuse package but in com.jboss.devstudio.fuse package.
