cfgmgr32.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like cfgmgr32.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like DynDrvUpd.exe - to follow. These files were created so that multiple programs (eg. SCR3310 USB Smart Card Reader drivers) could share the same cfgmgr32.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 cfgmgr32.dll is attempted to be loaded either when SCR3310 USB Smart Card Reader drivers is starting up, or in some cases already running. Some of the most common cfgmgr32.dll errors include:
- Access Violation at address - cfgmgr32.dll.
- cfgmgr32.dll could not be found.
- Cannot find C:\Program Files (x86)\SCM Microsystems\Tools\PCSCDiag\cfgmgr32.dll.
- Cannot register cfgmgr32.dll.
- Cannot start SCR3310 USB Smart Card Reader drivers. A required component is missing: cfgmgr32.dll. Please install SCR3310 USB Smart Card Reader drivers again.
- Failed to load cfgmgr32.dll.
- The application has failed to start because cfgmgr32.dll was not found.
- The file cfgmgr32.dll is missing or corrupt.
- This application failed to start because cfgmgr32.dll was not found. Re-installing the application may fix this problem.
Your cfgmgr32.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with SCR3310 USB Smart Card Reader drivers), or deleted by a malware infection. Furthermore, cfgmgr32.dll file corruption could be caused from a power outage when loading SCR3310 USB Smart Card Reader drivers, system crash while loading cfgmgr32.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.
