Visual Studio: MSB3073 error exited with code 1

This is an old post, but I encountered the same problem when I attempted to install OpenCV for Windows 10 using VS 16 2019 in a folder close to the root of C:.

Solution: Open cmd as administrator, open the SLN-project (In my case <OpenCV.sln>), and run Build on INSTALL. That worked like a charm.

What about specifying another value for CMAKE_INSTALL_PREFIX in the CMake GUI? That means, a directory where you definitely have write access.
