Cannot find the file'C:\WINDOWS\rundll32.exe' (or one of its components). Make sure the path and file name are correct and that all required libraries are available.

This happens when I open control panel. I'm on windows 98.

insert your Windows CD ROM disk in the CD ROM drive. Click Start|Run, type in:

expand X:\i386\rundll32.ex_ c:\windows\rundll32.exe

in the Open box, (where "X:" is the letter of your CD ROM drive), and press [Enter]. When it's done, restart your computer.
