Running multiple Synapse Versions
The setup guides you through the installation of Synapse inside your
%appdata%directory, however this means all servers are using the same directory and therefore the same Synapse.dll.
You can avoid this problem by placing the Synapse folder inside your server files directory besides the Local-/Multi- Admin.
By doing this all Servers running with those server files will use this local Synapse file.
This means you also need to install the entire game server multiple times.
