amrdec.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like amrdec.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. MP3 to Ringtone Gold) could share the same amrdec.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 amrdec.dll is attempted to be loaded either when MP3 to Ringtone Gold is starting up, or in some cases already running. Some of the most common amrdec.dll errors include:
- Access Violation at address - amrdec.dll.
- amrdec.dll could not be found.
- Cannot find C:\Windows\SysWOW64\amrdec.dll.
- Cannot register amrdec.dll.
- Cannot start MP3 to Ringtone Gold. A required component is missing: amrdec.dll. Please install MP3 to Ringtone Gold again.
- Failed to load amrdec.dll.
- The application has failed to start because amrdec.dll was not found.
- The file amrdec.dll is missing or corrupt.
- This application failed to start because amrdec.dll was not found. Re-installing the application may fix this problem.
Your amrdec.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with MP3 to Ringtone Gold), or deleted by a malware infection. Furthermore, amrdec.dll file corruption could be caused from a power outage when loading MP3 to Ringtone Gold, system crash while loading amrdec.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.
