decm_dff.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like decm_dff.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. EZ CD Audio Converter) could share the same decm_dff.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 decm_dff.dll is attempted to be loaded either when EZ CD Audio Converter is starting up, or in some cases already running. Some of the most common decm_dff.dll errors include:
- Access Violation at address - decm_dff.dll.
- decm_dff.dll could not be found.
- Cannot find C:\Program Files\EZ CD Audio Converter\decm_dff.dll.
- Cannot register decm_dff.dll.
- Cannot start EZ CD Audio Converter. A required component is missing: decm_dff.dll. Please install EZ CD Audio Converter again.
- Failed to load decm_dff.dll.
- The application has failed to start because decm_dff.dll was not found.
- The file decm_dff.dll is missing or corrupt.
- This application failed to start because decm_dff.dll was not found. Re-installing the application may fix this problem.
Your decm_dff.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with EZ CD Audio Converter), or deleted by a malware infection. Furthermore, decm_dff.dll file corruption could be caused from a power outage when loading EZ CD Audio Converter, system crash while loading decm_dff.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.
