Hello Ms Barbara, Thank you very much for your advise. I have tried all the methods you proposed, but still having the same error message. Anyway, I tried to delete Win32s and re-install VFP and everything works fine. Note : Win32s must be deleted first before re-install VFP, otherwise VFP will not overwrite the corrupted Win32s files. Once again thank you Barbara. Cheers, /Alvin :-)) > >I tried to run an .EXE file that I had built(VFP 3.0 in Win 3.11). > >It showed "Invalid or missing .EXE file".
