Firstly, you need to find out where ps2pdf is on your machine. It's in the Ghostscipt lib directory, which is probably something like C:\Program Files\gs\gs8.71\lib

Then you need to add this to the system Path: from the Start button, go to Settings, Control Panel, System, Advanced, Enviroment Variables, then select Path in the bottom panel, click Edit, and (in the ridiculously small edit box provided) add a semicolon to the end of whatever's there at the moment, and then add C:\Program Files\gs\gs8.71\lib (or whatever it is on your machine).

You will also need to add the Ghostscipt bin directory to the system Path. (This will be the same as the lib directory, but ending in bin rather than lib.)
