To install the Launcher, put NeosLauncher.exe into the same folder as your hl2.exe or left4dead.exe or left4dead2.exe Use this exe as the Desktop Link for the Game. When you start it, it will automatically create all files it needs in it´s folder (If the files do not already exist). When you launch it the first time, you will be asked to do the advanced settings (later you will find them in SetUp->Advanced). Make sure that the game exe set in the settings box is the right one. Now, enjoy the game! IMPORTANT (only L4D2 Launcher) To get the maps of the new campaign "The Passing", follow these steps -go to SetUp -> Map List Editor -go to the first game mode -click "Reset original maps" -repeat this for all game modes. If this doesn't work, try this: -export all your custom maps -click "open L4D2 folder" -close the launcher -execute the "NeosLauncher_Maplist_Reset.bat" file by doubleclicking on it -start the launcher -import all the saved custom maps
