I've reached the point where I need to install snort itself using this:
At the CMD prompt type 'd:\temp\snort_2_9_5_5_installer.exe' (less the outside quotes), and tap the 'Enter' key.
windows doesn't know how to handle the file which is listed as .exe in the guide, but file on my computer. this is the file downloaded from the guide? does anyone have any experience here?
