In your 3-Waves.cmd script, you install dotNetFx35_x86_x64 and NDP462-x86-x64-ENU, but you don’t install DirectX_Redist_Repack_x86_x64, even though it’s included in the files. Why isn’t it being installed?
It is one of those things that don't get updates so it is enough to install it once. I also don't know how to effectively check if it is installed or not so that I don't try to install it every time. So it is short of there for manual installation if you prefer. I had completely forgotten about it. I will try to figure it out. Thank you for reminding me!
