hello. I have used open cv before and managed to run the projects however I have reinstalled the updated version (430). it is running on windows 10 visual studio 19 as it was be fore but when I try to execute the code now it opens the window then give the system error of 'the code execution cannot proceed because opencv_core.dll was not found. reinstalling the program may fix this problem.' I am using the sample code on the 'How to build applications with OpenCV inside the "Microsoft Visual Studio"' page and I have tried reinstalling both open cv and visual studios . I have checked the project-> properties ->VC++ Directories-> include directories and library directories as well as Linker-> input->input -> additional directories and so far every thing seems to be correct. Please could you point me in the right direction I have checked a number of other forums that have all been a different version of opencv and dint seem to aid me.
