you don't install anything, they are "portable"
but if you have trouble downloading it use these steps:
for "nuget" site, on right side there is DOWNLOAD PACKAGE to click on
it will give you a .nupkg file to download, open it with your archiver (this is basically .zip file)
go to "bin\x64" folder
extract all dll files next to a (game) exe file you need to run
for "overhack" site
go to https://github.com/hejmus/win10verhack/releases/tag/v0.1
and download v0.1-winx64-rel.zip
also extract it all to your game exe folder
then run as it is described (using cmd)
withdll.exe /d:win10verhack64.dll <your_exe.exe>
