FC6- test 2: Error when trying to open any RPM or when trying to run system-install-packages

[Arch Willingham]

Any time I dbl click on an RPM file or try to run "/usr/sbin/system-install-packages", it gives me an exception occured error. 
This is the error:

[root at localhost ~]# /usr/sbin/system-install-packages /?

Any ideas?
