> [@Problem with curl.exe (Windows) and package installation](https://discourse.julialang.org/t/problem-with-curl-exe-windows-and-package-installation/29525/51):
>
> create a file called “\_curlrc” that contains “insecure” (wihout quote) and place it in your %APPDATA% (echo %APPDATA%). For windows, curlrc file should begin with underscore. [https://curl.haxx.se/docs/manual.html](https://curl.haxx.se/docs/manual.html)
