I guess we need to back up then and find out more about your system.
How much memory/disk space do you have?  What kind of CPU?  You're using
Windows 3.1 by itself (not running under some other operating system
like).  MPLAB needs a 386 or greater, about 4M of RAM, a few megs of
free disk space.  Did the install work without any errors or messages
(or is it the install itself that is failing)?
