antlr.runtime.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like antlr.runtime.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. Desktop iCalendar Lite) could share the same antlr.runtime.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 antlr.runtime.dll is attempted to be loaded either when Desktop iCalendar Lite is starting up, or in some cases already running. Some of the most common antlr.runtime.dll errors include:
- Access Violation at address - antlr.runtime.dll.
- antlr.runtime.dll could not be found.
- Cannot find C:\Program Files\desksware\Desktop iCalendar Lite\antlr.runtime.dll.
- Cannot register antlr.runtime.dll.
- Cannot start Desktop iCalendar Lite. A required component is missing: antlr.runtime.dll. Please install Desktop iCalendar Lite again.
- Failed to load antlr.runtime.dll.
- The application has failed to start because antlr.runtime.dll was not found.
- The file antlr.runtime.dll is missing or corrupt.
- This application failed to start because antlr.runtime.dll was not found. Re-installing the application may fix this problem.
Your antlr.runtime.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Desktop iCalendar Lite), or deleted by a malware infection. Furthermore, antlr.runtime.dll file corruption could be caused from a power outage when loading Desktop iCalendar Lite, system crash while loading antlr.runtime.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.
