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