“Install” Phase - visual studio 2019 - acess denied


I have followed the git and cmake instructions, with out any errors. Now i’m in the installation phase. I have opened the “mavsdk_superbud” sln in visual studio 2019, and run it - as i normally build, but i get an error “unable to start program…access is denied”.

Is this how the install phase is done ? If so, what might cause the error ? If not, how is it done ?
