This message will appear if you run ccwallet.exe without telling it to do anything. In that case, it will simply terminate without taking any action. In order to get ccwallet to do something, you need to either (a) tell it to respond to interactive commands entered on the console; and/or (b) tell it to respond to RPC commands; and/or (c) give it a command on its command line.

Note that all of the batch files in the v.2.0.1 release include both --interactive and --wallet-rpc=1, so when these batch files run ccwallet, it will respond to both interactive console commands and RPC commands.
