In case, this is (again) a problem of downloading packages via curl you may try this:

> [@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)

Details on the solution are here:  
[https://curl.haxx.se/docs/manual.html](https://curl.haxx.se/docs/manual.html)  
I can not directly link to the section but you can search for “Config File” on this page.

And here

> <https://unix.stackexchange.com/questions/60750/does-curl-have-a-no-check-certificate-option-like-wget>

is some more information about possible locations of \_curlrc in windows. I would prefer  
`%USERPROFILE%` as folder to store \_curlrc, which typically is `C:\Users\YOUR_USER_NAME`
