What are commctllib.dll Error Messages?

Dynamic Link Library commctllib.dll Errors

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

• Access Violation at address - commctllib.dll.
• commctllib.dll could not be found.
• Cannot find C:\Program Files\Paragon Software\Backup and Recovery 16 Free\program\plugins\designer\commctllib.dll.
• Cannot register commctllib.dll.
• Cannot start Paragon Backup & Recovery. A required component is missing: commctllib.dll. Please install Paragon Backup & Recovery again.
• Failed to load commctllib.dll.
• The application has failed to start because commctllib.dll was not found.
• The file commctllib.dll is missing or corrupt.
• This application failed to start because commctllib.dll was not found. Re-installing the application may fix this problem.

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