DDPD64A.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like DDPD64A.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit)) could share the same DDPD64A.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when DDPD64A.dll is attempted to be loaded either when Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit) is starting up, or in some cases already running. Some of the most common DDPD64A.dll errors include:
- Access Violation at address - DDPD64A.dll.
- DDPD64A.dll could not be found.
- Cannot find C:\Windows\System32\DriverStore\FileRepository\hdxrt.inf_amd64_b0026a592e9b4de4\DDPD64A.dll.
- Cannot register DDPD64A.dll.
- Cannot start Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit). A required component is missing: DDPD64A.dll. Please install Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit) again.
- Failed to load DDPD64A.dll.
- The application has failed to start because DDPD64A.dll was not found.
- The file DDPD64A.dll is missing or corrupt.
- This application failed to start because DDPD64A.dll was not found. Re-installing the application may fix this problem.
Your DDPD64A.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit)), or deleted by a malware infection. Furthermore, DDPD64A.dll file corruption could be caused from a power outage when loading Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit), system crash while loading DDPD64A.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
