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