Hello - I have problem with the "Windows cannot find ...\system32\rundll32.exe" when I attempt to open the computer calendar, as well as anything within Control Panel. I can actually open Control Panel, but cannot open any applications within it. I followed the suggestions above, but when I attempted the fix with the "expand d:\i386\rundll.exe_.....", nothing happens.
I cant open anything. Only what i can open is GOOGLECHROME, and WINDOWS MEDIA PLAYER with some errors.
BTW, i dont want/i cant reinstall the windows.
I also tried to download the file " rundll32.exe " and replaced it with the one in the system32 folder. But still nothing.
Any ideas? Thanks so much for reading my plea! I would be very grateful for ANY ideas and suggestions to fix this!
HELP, PLEASE!

E: I also tried to restore the system, ( START > ALL PROGRAMS > SYSTEM TOOLS > SYSTEM RESTORE.
BUT when i wanted to open the " System Restore.exe " then i got the same problem as with everything.
Cant open any .exe file, besides GOOGLE CHROME.
