Is there a Windows installer?

[papamarkou]

@MikeInnes the IT staff in my school is trying to install Julia (and an IDE for it) so that postgraduate students can use it on Windows machines. Does Juno work well on Windows? There seems to be no download link for Juno (on Windows) here.

[pfitzseb]

Yeah, Juno does work pretty well on Windows -- the simplest way to install it is to actually just install Atom, Julia, and then this package here. So there's no need for an extra download for any OS.

If the instructions you linked above aren't clear enough, do you have any suggestions for improving them?

[papamarkou]

Great, thanks for your reply @pfitzseb. I will check with IT if this sorts things out, as I use a mac myself and can't check it directly on my own computer.

To follow up with this, the IT staff installed Julia on two Windows computers in the lab, and Julia works well. Furthermore, all the Atom packages were installed without issues, but Nettle, one of the Julia packages associated with Juno, failed. Here is the error I got:

Yep, that's an issue I had as well.

Basically, the problem is the IE's security config on Windows Server (as described here): You either have to turn it off or delete the caching stuff in WinRPM.jl's sources.list (which might be the easier/better solution until this issue is really fixed in WinRPM) as like this.

Hope this helps a bit!

[papamarkou]

Great, thanks a lot @pfitzseb, I will try out your solution next week once back at the office and will let you know how it goes.

[papamarkou]

Quick question @pfitzseb, did you mean that I should replace

https://cache.julialang.org/http://download.opensuse.org/repositories/windows:/mingw:/win32/openSUSE_13.2
https://cache.julialang.org/http://download.opensuse.org/repositories/windows:/mingw:/win64/openSUSE_13.2

by

https://julialang.org/http://download.opensuse.org/repositories/windows:/mingw:/win32/openSUSE_13.2
https://julialang.org/http://download.opensuse.org/repositories/windows:/mingw:/win64/openSUSE_13.2

If yes, at which stage should I do this? After the failure and then retry?

[pfitzseb]

No, you need to get rid of the redirection entirely, i.e. replace those URLs with

http://download.opensuse.org/repositories/windows:/mingw:/win32/openSUSE_13.2
http://download.opensuse.org/repositories/windows:/mingw:/win64/openSUSE_13.2

After the failure should be fine, yes, but doesn't really matter. As soon as that file has been created by the julia package manager, changing it is okay, I think.
