You dont install BMS over the top of the falcon 4.0 install, it is installed separately, into its own folder. To install it you need to download it, and run the setup executable included with it. The setup will ask where the original falcon 4.0 executable is, and you will have to select your falcon 4.0 install directory to progress. After that it will install BMS. Good luck!
ty for the help dude!
i go to try it!
