What are rdd20ct.dll Error Messages?


Dynamic Link Library rdd20ct.dll Errors

rdd20ct.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like rdd20ct.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. Canon MP Navigator) could share the same rdd20ct.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 rdd20ct.dll is attempted to be loaded either when Canon MP Navigator is starting up, or in some cases already running. Some of the most common rdd20ct.dll errors include:

Your rdd20ct.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Canon MP Navigator), or deleted by a malware infection. Furthermore, rdd20ct.dll file corruption could be caused from a power outage when loading Canon MP Navigator, system crash while loading rdd20ct.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.
