UpLib.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like UpLib.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like wuauclt.exe - to follow. These files were created so that multiple programs (eg. KMPlayer) could share the same UpLib.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 UpLib.dll is attempted to be loaded either when KMPlayer is starting up, or in some cases already running. Some of the most common UpLib.dll errors include:
- Access Violation at address - UpLib.dll.
- UpLib.dll could not be found.
- Cannot find C:\Program Files\KMPlayer 64X\UpLib.dll.
- Cannot register UpLib.dll.
- Cannot start KMPlayer. A required component is missing: UpLib.dll. Please install KMPlayer again.
- Failed to load UpLib.dll.
- The application has failed to start because UpLib.dll was not found.
- The file UpLib.dll is missing or corrupt.
- This application failed to start because UpLib.dll was not found. Re-installing the application may fix this problem.
Your UpLib.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with KMPlayer), or deleted by a malware infection. Furthermore, UpLib.dll file corruption could be caused from a power outage when loading KMPlayer, system crash while loading UpLib.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.
