opencv_world400.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like opencv_world400.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like ACDSeeCommanderHome23.exe - to follow. These files were created so that multiple programs (eg. ACDSee Photo Studio Standard 2019) could share the same opencv_world400.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 opencv_world400.dll is attempted to be loaded either when ACDSee Photo Studio Standard 2019 is starting up, or in some cases already running. Some of the most common opencv_world400.dll errors include:
- Access Violation at address - opencv_world400.dll.
- opencv_world400.dll could not be found.
- Cannot find C:\Program Files\ACD Systems\ACDSee Home\23.0\opencv_world400.dll.
- Cannot register opencv_world400.dll.
- Cannot start ACDSee Photo Studio Standard 2019. A required component is missing: opencv_world400.dll. Please install ACDSee Photo Studio Standard 2019 again.
- Failed to load opencv_world400.dll.
- The application has failed to start because opencv_world400.dll was not found.
- The file opencv_world400.dll is missing or corrupt.
- This application failed to start because opencv_world400.dll was not found. Re-installing the application may fix this problem.
Your opencv_world400.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with ACDSee Photo Studio Standard 2019), or deleted by a malware infection. Furthermore, opencv_world400.dll file corruption could be caused from a power outage when loading ACDSee Photo Studio Standard 2019, system crash while loading opencv_world400.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.
