xfcodec64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like xfcodec64.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like autoup.exe - to follow. These files were created so that multiple programs (eg. War Rock Client) could share the same xfcodec64.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 xfcodec64.dll is attempted to be loaded either when War Rock Client is starting up, or in some cases already running. Some of the most common xfcodec64.dll errors include:
- Access Violation at address - xfcodec64.dll.
- xfcodec64.dll could not be found.
- Cannot find C:\Windows\System32\xfcodec64.dll.
- Cannot register xfcodec64.dll.
- Cannot start War Rock Client. A required component is missing: xfcodec64.dll. Please install War Rock Client again.
- Failed to load xfcodec64.dll.
- The application has failed to start because xfcodec64.dll was not found.
- The file xfcodec64.dll is missing or corrupt.
- This application failed to start because xfcodec64.dll was not found. Re-installing the application may fix this problem.
Your xfcodec64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with War Rock Client), or deleted by a malware infection. Furthermore, xfcodec64.dll file corruption could be caused from a power outage when loading War Rock Client, system crash while loading xfcodec64.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.
