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