Some months ago I was using Julia and recently I wanted to pick it up again. I wanted a fresh version so I deleted my previous version and all packages I had.

Now, after installing the new version (0.6.2), I cannot use any Pkg. command : I will get the following error after using init, add or update

ERROR : GitError(Code:ECERTIFICATE, Class:OS, user cancelled certificate check :)

I have tried reinstalling to no avail.

I am on Windows; I have seen many related problems answered by git commands but I have no idea on how to use them because they all seem to be destined to Linux users.

Thanks in advance.
