RtkApi64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like RtkApi64.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 0009-64bit_Win7_Win8_Win81_Win10_R282.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 RtkApi64.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 RtkApi64.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 RtkApi64.dll errors include:
- Access Violation at address - RtkApi64.dll.
- RtkApi64.dll could not be found.
- Cannot find C:\Windows\System32\DriverStore\FileRepository\hdxrt.inf_amd64_b0026a592e9b4de4\RtkApi64.dll.
- Cannot register RtkApi64.dll.
- Cannot start Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit). A required component is missing: RtkApi64.dll. Please install Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit) again.
- Failed to load RtkApi64.dll.
- The application has failed to start because RtkApi64.dll was not found.
- The file RtkApi64.dll is missing or corrupt.
- This application failed to start because RtkApi64.dll was not found. Re-installing the application may fix this problem.
Your RtkApi64.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, RtkApi64.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 RtkApi64.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.
