There are many ways to do this, but none is easier. Basically,
you should try to make your machine's file system available to the machine where you want to install the software.
If you have a time, bandwidth and know-how, you could try setting up a FTP/HTTP server in your box so that you can access it from the other machine just like any other website/server. Or you could simply burn a CD and install from it.
Cheers.
