How to Fix MFC100U.dll Missing Errors

I just installed a software for many times, however, I always received the following error message "This application failed to start because MFC100U.dll was not found. Re-installing the application may fix this problem." I've tried to download the MFC100U.dll file by myself. It didn't work! I don't know if I have done the right thing. How should I do?
