libunarr-ics.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libunarr-ics.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Free AVI Player) could share the same libunarr-ics.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 libunarr-ics.dll is attempted to be loaded either when Free AVI Player is starting up, or in some cases already running. Some of the most common libunarr-ics.dll errors include:
- Access Violation at address - libunarr-ics.dll.
- libunarr-ics.dll could not be found.
- Cannot find C:\Program Files (x86)\K-Lite Codec Pack\Icaros\64-bit\libunarr-ics.dll.
- Cannot register libunarr-ics.dll.
- Cannot start Free AVI Player. A required component is missing: libunarr-ics.dll. Please install Free AVI Player again.
- Failed to load libunarr-ics.dll.
- The application has failed to start because libunarr-ics.dll was not found.
- The file libunarr-ics.dll is missing or corrupt.
- This application failed to start because libunarr-ics.dll was not found. Re-installing the application may fix this problem.
Your libunarr-ics.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Free AVI Player), or deleted by a malware infection. Furthermore, libunarr-ics.dll file corruption could be caused from a power outage when loading Free AVI Player, system crash while loading libunarr-ics.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.
