mfcdata.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mfcdata.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like klist.exe - to follow. These files were created so that multiple programs (eg. Adobe Flash Professional CC) could share the same mfcdata.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 mfcdata.dll is attempted to be loaded either when Adobe Flash Professional CC is starting up, or in some cases already running. Some of the most common mfcdata.dll errors include:
- Access Violation at address - mfcdata.dll.
- mfcdata.dll could not be found.
- Cannot find C:\Program Files\Adobe\Adobe Animate CC 2019\mfcdata.dll.
- Cannot register mfcdata.dll.
- Cannot start Adobe Flash Professional CC. A required component is missing: mfcdata.dll. Please install Adobe Flash Professional CC again.
- Failed to load mfcdata.dll.
- The application has failed to start because mfcdata.dll was not found.
- The file mfcdata.dll is missing or corrupt.
- This application failed to start because mfcdata.dll was not found. Re-installing the application may fix this problem.
Your mfcdata.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Adobe Flash Professional CC), or deleted by a malware infection. Furthermore, mfcdata.dll file corruption could be caused from a power outage when loading Adobe Flash Professional CC, system crash while loading mfcdata.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.
