I tried the fix program, but when I again tried to run sysedit, a window called System Configuration Editor opened.  It contained 4 windows:  System.ini, Win.ini, Config.sys and Autoexec.bat and an error message that said C:\AUTOEXEC.BAT  Cannot open this file.

config.sys and autoexec.bat windows are empty.  System.ini contains:
