radecoderEx.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like radecoderEx.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. Mobizen PC) could share the same radecoderEx.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 radecoderEx.dll is attempted to be loaded either when Mobizen PC is starting up, or in some cases already running. Some of the most common radecoderEx.dll errors include:
- Access Violation at address - radecoderEx.dll.
- radecoderEx.dll could not be found.
- Cannot find C:\Program Files (x86)\RSUPPORT\Mobizen\radecoderEx.dll.
- Cannot register radecoderEx.dll.
- Cannot start Mobizen PC. A required component is missing: radecoderEx.dll. Please install Mobizen PC again.
- Failed to load radecoderEx.dll.
- The application has failed to start because radecoderEx.dll was not found.
- The file radecoderEx.dll is missing or corrupt.
- This application failed to start because radecoderEx.dll was not found. Re-installing the application may fix this problem.
Your radecoderEx.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Mobizen PC), or deleted by a malware infection. Furthermore, radecoderEx.dll file corruption could be caused from a power outage when loading Mobizen PC, system crash while loading radecoderEx.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.
