In order to install this lesson, you will need to create a new directory on your hard drive, download a self extracting, compressed file into this directory, and then run this file in order to extract the data and program files.

1. create a directory on your computer to hold this lesson.  For example, open a Command Prompt window and type:

       cd \
       mkdir xyzvisit
You can also do this using the Windows Explorer  or My Computer.
 
2. get the self extracting ZIP file (it is almost 20MB) from here:

       XYZvisit.exe
 
3. be sure to put this file into the same directory  you created in step 1.

 
4. to extract all the image and program files, just run the XYZvisit.exe file by either:
• opening My Computer  or the Windows Explorer and clicking on the filename XYZvisit.exe
                                            OR
• opening a Command Prompt window, cd \xyzvisit, and then typing: XYZvisit

              visit.bat

filename from My Computer  or Windows Explorer, or open a Command Prompt window, and type:

              cd \xyzvisit
              visit

During the lesson, if a message "Communications problem - restart" appears at the bottom of the window, then you will need to close out that window (double click over the icon in the upper left corner), and then enter the visit command again.

In the window where you enter the visit command, you will see various communications message appearing; for the most part, you should ignore these.
