The system uses the DLL file Sequence

When the system tries to load the file to the process address space through the DLL file name, it looks for the DLL file path in the following order:
· ProgramThe directory where the execution file is located;
· Current program working directory
· System directory: For Windows95/98, you can call the getsystemdirectory function. For WindowsNT/2000, it refers to the 32-bit Windows System directory, you can also call the getsystemdirectory function to obtain the value system32.
· Windows Directory
· All directories listed in the PATH environment variable
