aida_cpl.cpl is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like aida_cpl.cpl, 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. AIDA64 Extreme) could share the same aida_cpl.cpl 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 CPL 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 aida_cpl.cpl is attempted to be loaded either when AIDA64 Extreme is starting up, or in some cases already running. Some of the most common aida_cpl.cpl errors include:
- Access Violation at address - aida_cpl.cpl.
- aida_cpl.cpl could not be found.
- Cannot find C:\Program Files (x86)\FinalWire\AIDA64 Extreme\aida_cpl.cpl.
- Cannot register aida_cpl.cpl.
- Cannot start AIDA64 Extreme. A required component is missing: aida_cpl.cpl. Please install AIDA64 Extreme again.
- Failed to load aida_cpl.cpl.
- The application has failed to start because aida_cpl.cpl was not found.
- The file aida_cpl.cpl is missing or corrupt.
- This application failed to start because aida_cpl.cpl was not found. Re-installing the application may fix this problem.
Your aida_cpl.cpl file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with AIDA64 Extreme), or deleted by a malware infection. Furthermore, aida_cpl.cpl file corruption could be caused from a power outage when loading AIDA64 Extreme, system crash while loading aida_cpl.cpl, 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.
