Trouble building OpenCV from source with Gstreamer and more trouble installing from Visual Studio

I have tried to uninstall Python 64 bit and replace with 32 bit binaries. I’ve tried installing with and w/o admin privileges. Ive moved the location of the build directory from a /user/… to c:.…

I tried to install on a different computer. All the same outcome. Missing dll

My machine is 64 bit Windows 10 uptodate with c++ redirect, media files, etc…
