A. Antivirus Deletion (The #1 Cause)
Modern antivirus software (Windows Defender, Avast, Norton, etc.) aggressively targets files named rld.dll. Because this specific filename is historically associated with game cracking groups (like RELOADED), antivirus programs flag it as a "HackTool," "Trojan," or "PUP" (Potentially Unwanted Program).
B. Incorrect Directory Path
PES 2012 requires the .dll file to be in the same folder as the executable (usually pes2012.exe). If the file is located in a subfolder (like a "Crack" folder inside the installation directory) but not moved to the root folder, the game cannot see it.
C. DEP (Data Execution Prevention)
Windows has a security feature called DEP that monitors memory usage. Older games and certain cracked executables perform memory modifications that DEP views as suspicious. If DEP blocks the rld.dll from executing code, the load fails. the dynamic library rld.dll failed to load pes 2012
D. Missing Visual C++ Redistributables
While less specific to this error message, the rld.dll relies on system libraries to function. If your PC is missing the legacy Visual C++ runtimes (specifically 2005, 2008, or 2010), the DLL cannot initialize.
Try running PES 2012 in compatibility mode: The dynamic library rld
Before we fix it, it helps to understand the culprit.
The file rld.dll is a dynamic link library file that PES 2012 uses for its security and licensing verification (it is often associated with SecuROM or similar copy protection mechanisms). What happens: The antivirus silently deletes the file
There are three main reasons why your computer suddenly "loses" this file:
rld.dll file as a "crack" or malware (a "false positive") and silently quarantines or deletes it.
