@msmcleod sequencly to your great information, I tried to install online Edge Browser, and with much surprise, also this program installation failed because coudn' t connect to internet! I think this is the bug to solve. I will then try to update Win 7 and fix the TLS, and try again, hopefully to solve the issue. Please, do you know which TLS version is the latest for Windows 7? Is that TSL 1.2 or 1.3?
