GNO versions 2.0.2 through 2.0.4 were distributed as sequential updates to version 2.0.1, rather than as complete distributions. Consequently, you should install each of the version 2.0.2, 2.0.3, and 2.0.4 distributions, in sequence, over top of your version 2.0.1 distribution.
You should also obtain and install the Multi-User Update.
