First, why not post your question in the Lapper section of this forum?
The basics to get Lapper going are straight forward:
- Open an Insim port on your server using command: /insim 29999
- Open file 'default_1.ini' which can be found in folder 'bin\default'
- Put in your admin password where it says 'AdminPassHere'
- Save the file
- Start Lapper using the LFSLapper.exe
Now you should have the 'out of the box' configuration of Lapper running on your server.
