What are agcore.dll Error Messages?


Dynamic Link Library agcore.dll Errors

agcore.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like agcore.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. Microsoft Silverlight) could share the same agcore.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 agcore.dll is attempted to be loaded either when Microsoft Silverlight is starting up, or in some cases already running. Some of the most common agcore.dll errors include:

Your agcore.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Silverlight), or deleted by a malware infection. Furthermore, agcore.dll file corruption could be caused from a power outage when loading Microsoft Silverlight, system crash while loading agcore.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.

CAUTION : We strongly advise against downloading and copying agcore.dll to your appropriate Windows system directory. Microsoft typically does not release Microsoft Silverlight DLL files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing agcore.dll and all other DLL files for Microsoft Silverlight. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
