What are PCCompanion.dll Error Messages?


Dynamic Link Library PCCompanion.dll Errors

PCCompanion.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like PCCompanion.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Sony PC Companion) could share the same PCCompanion.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 PCCompanion.dll is attempted to be loaded either when Sony PC Companion is starting up, or in some cases already running. Some of the most common PCCompanion.dll errors include:

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