Metadata analysis shows opencv_flann455.dll is a Dynamic Link Library (DLL) for OpenCV library and is described as “OpenCV module: Clustering and Search in Multi-Dimensional Spaces” .

DLL files (Dynamic Link Libraries) are shared core modules used by Windows programs to run efficiently without duplicating code. Most errors occur because the DLL is missing, corrupted, or outdated. In many cases, reinstalling the related application, repairing Windows, or replacing the DLL resolves the issue.

How do I fix missing DLL errors?
1

Software Fix

Fully uninstall and reinstall the program causing the error. If you are not sure what program is broken, look at the available file metadata above for hints. If a clean reinstall fails, download and install the DLL file manually.

64-bit → C:\Windows\System32
3
