mfc45.dat is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mfc45.dat, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like mrt.exe - to follow. These files were created so that multiple programs (eg. System Mechanic Free) could share the same mfc45.dat 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 DAT 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 mfc45.dat is attempted to be loaded either when System Mechanic Free is starting up, or in some cases already running. Some of the most common mfc45.dat errors include:
- Access Violation at address - mfc45.dat.
- mfc45.dat could not be found.
- Cannot find C:\Windows\SysWOW64\mfc45.dat.
- Cannot register mfc45.dat.
- Cannot start System Mechanic Free. A required component is missing: mfc45.dat. Please install System Mechanic Free again.
- Failed to load mfc45.dat.
- The application has failed to start because mfc45.dat was not found.
- The file mfc45.dat is missing or corrupt.
- This application failed to start because mfc45.dat was not found. Re-installing the application may fix this problem.
Your mfc45.dat file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with System Mechanic Free), or deleted by a malware infection. Furthermore, mfc45.dat file corruption could be caused from a power outage when loading System Mechanic Free, system crash while loading mfc45.dat, 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.
