AutoUpdatePlugin.cpl is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like AutoUpdatePlugin.cpl, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. QuarkXPress) could share the same AutoUpdatePlugin.cpl 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 CPL 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 AutoUpdatePlugin.cpl is attempted to be loaded either when QuarkXPress is starting up, or in some cases already running. Some of the most common AutoUpdatePlugin.cpl errors include:
- Access Violation at address - AutoUpdatePlugin.cpl.
- AutoUpdatePlugin.cpl could not be found.
- Cannot find C:\Windows\System32\AutoUpdatePlugin.cpl.
- Cannot register AutoUpdatePlugin.cpl.
- Cannot start QuarkXPress. A required component is missing: AutoUpdatePlugin.cpl. Please install QuarkXPress again.
- Failed to load AutoUpdatePlugin.cpl.
- The application has failed to start because AutoUpdatePlugin.cpl was not found.
- The file AutoUpdatePlugin.cpl is missing or corrupt.
- This application failed to start because AutoUpdatePlugin.cpl was not found. Re-installing the application may fix this problem.
Your AutoUpdatePlugin.cpl file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with QuarkXPress), or deleted by a malware infection. Furthermore, AutoUpdatePlugin.cpl file corruption could be caused from a power outage when loading QuarkXPress, system crash while loading AutoUpdatePlugin.cpl, 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.
