cdid3.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like cdid3.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like AppInstaller.exe - to follow. These files were created so that multiple programs (eg. Wondershare UniConverter) could share the same cdid3.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 cdid3.dll is attempted to be loaded either when Wondershare UniConverter is starting up, or in some cases already running. Some of the most common cdid3.dll errors include:
- Access Violation at address - cdid3.dll.
- cdid3.dll could not be found.
- Cannot find C:\Program Files (x86)\Wondershare\Video Converter Ultimate\cdid3.dll.
- Cannot register cdid3.dll.
- Cannot start Wondershare UniConverter. A required component is missing: cdid3.dll. Please install Wondershare UniConverter again.
- Failed to load cdid3.dll.
- The application has failed to start because cdid3.dll was not found.
- The file cdid3.dll is missing or corrupt.
- This application failed to start because cdid3.dll was not found. Re-installing the application may fix this problem.
Your cdid3.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Wondershare UniConverter), or deleted by a malware infection. Furthermore, cdid3.dll file corruption could be caused from a power outage when loading Wondershare UniConverter, system crash while loading cdid3.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.
