This will lead you to Github where at the bottom of the page at the section ''Assets'' you want to download the ''alterware-launcher.exe''.
After downloading the exe. you have to move this exe. to your MW2 root folder and run it.

If you don't know how to find the folder, you can do this by going to your steam library and going to MW2, then click on the cog on the right, go to files and then browse local files.

The launcher may prompt you with a few questions designed to assist you in setting it up correctly. Once the update process is complete, the AlterWare client for the current game should open automatically.

Go to https://www.moddb.com/mods/bot-warfare/downloads and download the latest version of botwarfare for MW2.
