first.. when you make a command, do not put any spaces in the name. also, commands are case sensitive... so do not use any cap letters.

next, when you make a command for wow, and hit the 'program...' button, do not select launcher.exe. you want to find wow.exe in the same folder.

launcher.exe is the updater, not the client. you want to run the client.

keep in mind, every tuesday after an update, you must run launcher.exe to update the files in each wow folder. after that, you can run the command as normal.

i hope that helps
