How to run ncompact from a command prompt on system databases on a partitioned server?

I shut down one partitioned server.
Opened a command prompt (run as administrator)
changed my directory to the data directory of the partition
ran the following command which results in a crash screen popping up:
c:\hcl\domino\ncompact -c names.nsf

I must be doing something wrong. What am I missing?
