How to fix missing or corrupt DLL errors?

[mellowtitle]

Hi everyone

Recently, I encountered an error of missing some DLL files when running software on Windows. I tried downloading the missing DLL files from some websites and placing them in the system folder, but the error was still not completely fixed. Is there a more reliable way to fix this error without affecting the system? Also, is there any tool that can automatically detect and fix DLL errors safely? Looking forward to receiving advice from everyone.

Thanks in advance!
