You are now ready to start a game. In WinAGI, go to "Game" > "New Game" > "From Template" and choose "Version2". Select a folder for your new game outside of either Program Files directories, say in a new folder in your Documents folder and click OK.
Once the new game is open, go to "Game" > "Properties". Click the browse button for the "Game Executable" and select "RUN.EXE" inside of the game's folder.
You will have a new game ready for you to begin developing. Clicking the run button will automatically start the game in DOSBox so you can test your work.
