How to get the package manager to work?

Hello there!

I´m using QNX and all the linux things not very often, so I´m really a
newbie to
Unix-like systems.

I´ve burned the 256MB ISO onto a CD and installed my QNX with the
Windows-Installer.
The system itself runs very fine, but as I started the package manager to
install some packages
from the CD it doesn´t work! My respositories on the CD are:

/fs/cd0/REPOSITORY

and

/fs/cd0/REPOSITORY2

When I added a new archive in the manager with these paths and double
clicked on
it, NO software and new archives appeared! What I´m doing wrong? Maybe
somebody can help me!

Thank you,
Andy
