Good investigation, well done ! You helped me and I thank you for that.
I’m having the same problem, could you expand in your solution explanation? I don’t understand how setup the Internet Explorer in Windows 10 can solve an Internet connection issue with MinGW Installation Manager. Thanks in advance.
Hello, I added how to find and change this settings.
It works because MinGW is using the Internet Explorer DLL to access the Internet (and so the Internet settings) and I think that MinGW gets a warning when switching from secure and not secure mode and it doesn’t handle it correctly.
