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

   Download the zip archive Perple_X_#.#.#_[*]WINDOWS_**bit.zip, 

   where:

        #.#.# is the version number (e.g., 6.8.6).

        [*]   is "small_" for versions compiled for computers with limited RAM, these
              versions should only be used if the normal versions won't run on your
              computer.

        **    is 32 or 64 and indicates whether the code was compiled for 32 or 64 bit 
              computers, use the 32 bit version if you do not know whether your computer 
              is 32 or 64 bit. 

   The zip archives contain the Perple_X programs, extract these to a single 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/Increase_page_file_size_in_windows.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.
