plugin_msn.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like plugin_msn.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. Garena+) could share the same plugin_msn.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 plugin_msn.dll is attempted to be loaded either when Garena+ is starting up, or in some cases already running. Some of the most common plugin_msn.dll errors include:
- Access Violation at address - plugin_msn.dll.
- plugin_msn.dll could not be found.
- Cannot find C:\Program Files (x86)\Garena Plus\xim\plugin_msn.dll.
- Cannot register plugin_msn.dll.
- Cannot start Garena+. A required component is missing: plugin_msn.dll. Please install Garena+ again.
- Failed to load plugin_msn.dll.
- The application has failed to start because plugin_msn.dll was not found.
- The file plugin_msn.dll is missing or corrupt.
- This application failed to start because plugin_msn.dll was not found. Re-installing the application may fix this problem.
Your plugin_msn.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Garena+), or deleted by a malware infection. Furthermore, plugin_msn.dll file corruption could be caused from a power outage when loading Garena+, system crash while loading plugin_msn.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.
