the program was tested in my machine with VS.net installed. It run without any problem with 24 hours.
However, when I run it in other machine without VS.NET or VC ienvironment,
it didn't works. Even I installed dot.net framework and copy MFC, VC's dll files to this PC, it just don;t run.

Umm, I don't think there is much we can do for you without some idea of what the program is. Could you please provide us with the code or if there is too much code, information on what the program is supposed to do as well as the exact text of the error message?

Sorry...here are the error message..

I thing the problem is not a missing dll,
but confliction between the runtime libraries.
I will check whether the "error reporting" is enabled in both machine when I have time.

My guess is that it is not enabled in the system which shows no error,
but enabled in the one that shows error.
If so, I need to correct your program.

Hmm, two things I noticed, one, the okay button is in asian characters and the text is in English, do you have windows set up for an asian language, or is this a weird fluke. Two, the "unusual way" part of the message. See if you can write an error trap in the program (In VB it's on error goto, I don't remember for VC) and get it to output the a) error message and exit code of the program.
