How to avoid "all in one" Momentics installation?

Hi
I try to install Momentics NC and get only one big bundle in qnxinstall that
contains all repository packages.
Even after installation there is the same big solid piece containing games,
development tools and so on.
How can I easily uninstall separate packages? And where is there high
modularity that was in 6.1 version and old installer?

Thanks,

Boris
