1) Go to www.perplex.ethz.ch/perplex/ibm_and_mac_archives/WINDOWS

   Download the zip archive Perple_X_#.#.#_WINDOWS_64bit.zip, where #.#.# is the 
   release number (e.g., 7.1.8).

   The zip archives contain the Perple_X programs, extract these to what will be 
   your Perple_X directory.

2) Extract the Perple_X data files in
 
   www.perplex.ethz.ch/perplex/ibm_and_mac_archives/Perple_X_#.#.#_data_files.zip 

   to the same directory as in step 1. Select the version #.#.# closest to the
   program version #.#.# in step 1.

3) For information on aspects of configuring your system to run Perple_X see

   www.perplex.ethz.ch/perplex/faq/running_from_a_windows_console.txt
   www.perplex.ethz.ch/perplex/faq/viewing_file_types_in_windows.txt

   To use Perple_X effectively it is important that you run the programs from a 
   console (aka shell, terminal, or command window). Clicking on the program icons is 
   a bad way to run the programs because it is likely you will miss error 
   and warning messages.
