Hi José,
you can install multiple instances of the Spectrum Connector (even on the same server).
Start the intaller a second time, and it will ask you if you want to install a second instance.
As additional information:
The connection to the first Spectrum Server must be active, or the installer will exit, because it checks the already defined instances (in case you want to use the installer to Repair the installation).
