To extract the password protected files in this ZIP file,
first move the file to the directory where the program included 
is located. Then give the command:

PKUNZIP zipfilename -s

You'll be prompted to enter a password. Enter the password I 
gave you, exactly as I gave it to you. It must be all in 
lower-case letters.

Then, confirm overwriting files.
 
Finally, move all .DLL and .VBX files from the archive into your 
WINDOWS\SYSTEM directory after they are extracted. DOS 6.x commands 
for this are:

MOVE *.DLL C:\WINDOWS\SYSTEM
MOVE *.VBX C:\WINDOWS\SYSTEM
