- Saved the "vs_professional.exe" in my user Download directory, didn't work in any other disk or path.
- Installed the certificate, without the reboot.
- Executed the customized (2 languages and some workloads) command from administrative Command Prompt window targetting an offline root folder on a secondary disk "E:\vs2017offline".
Never thought MS could distribute this way, I understand that people downloading Visual Studio should have advanced knowledge of computers and OS but this is like a jump in time to 30 years back.
