Old cracks often require elevated privileges to hook into the game process.
settings.exe (though not mandatory, it helps).Open Command Prompt as Administrator and run:
regsvr32 rld.dll
(but note: game cracks often don't register like normal DLLs)
rld.dll relies on Microsoft Visual C++ runtime libraries. If these are missing or corrupt, the DLL will fail to initialize (Error E4).
This is a separate issue, but often follows the E4 fix. Run settings.exe in the PES folder. Go to the Specs tab. Uncheck "Wait for V-sync" and lower your resolution. Set your desktop scaling to 100%.
Before we begin, a serious warning. You will find hundreds of websites offering a "free rld.dll download." Never do this. Downloading standalone DLLs from untrustworthy sources is the #1 way to get malware, trojans, or keyloggers on your PC. We will solve this without resorting to shady downloads.
