Download the bot. Unzip it. Then you can update it. Choose your private server version and update.
Change the name of the folder to macth your private server version.
Then you can unpack the zip file again, and update it for another version of wow, etc...
So basically you can have mutltiple versions of wrobot. Just rename the folders with the version you updated. wrobotLK, wrobotTBC, wrobotLegal ....
Then just start the wrobot.exe in the folder you need for the game you play.
