This section is for release of
CO2 Bots & Macros
Post questions in

next time.
Anyway here is a quick answer.
What you have to do with the macro/bot u downloaded after you have the file on your desktop depends in what language was made and what type of bot is it.
Some macros require a main program to run such as quickmacro/macro express
Some other are standalone and pixelbased like those made on AutoIt or AutoHotKey.
Some others require net framework to run.
So if you don't know how to run a macro/bot you got I recommend you to read other comments on the topic where u got the file and if you don't find the information you can make the question on the same topic so the threadstarter (probably the bot maker) can help you.
Hope that helps.
Good luck.
