How can I identify which specific DLL file is causing the "cannot import dll" error?

Often, the error message itself will explicitly state the name of the missing or problematic DLL file (e.g., "The program can't start because [specific_dll_name].dll is missing from your computer"). If the error message is vague, you can use tools like **Dependency Walker (depends.exe)**. This free tool allows you to open an executable file and see all the DLLs it requires, highlighting any that are missing or have unresolved dependencies. Examining system logs (Event Viewer) in Windows 7 might also provide more detailed error information.
