... If there are any plugins that you need from those versions, you can add them later. It is possible to install individual plugins from the installer without installing the main program. ...
Great! But how do you do this?
Is this also possible for SPLAT, i.e. can I install components from X3?
You run the installer and choose Custom installation. You'll be shown a list of components which you can then select and install separately.
Yes, use this method to install components of X1/X2/X3 alongside SPLAT.
