Hello.

I could install and use GR (through Plots) on my Windows 10 X64 computer with Julia 1.0.2.  
But I’m not able to install it on the computer at work using Windows 7 x64.

I get this error:

I’ve tried both as administrator and as a user. I’ve tried applying exclusion rules on the antivirus and firewall. But nothing changes.

I don’t have problems installing other programs.

This may be the cure:

There is some SSL problem on your machine when the GR build script tries to download the run-time using a secure connection. As a result, `build.jl` tries an insecure connection, which seems to fail, too. It’s hard for me to identify the real problem as I can’t reproduce this behaviour.

Can you download the run-time from the command line (wget, curl or whatever)?

Could you tell me the command line to do it, please?

I don’t know why I didn’t have any problem with Julia 0.7.

I had another error after installing 1.02. I removed .julia completely and afterwards it worked.

Do you have additional info in `C:\Users\med\.julia\packages\GR\k8wwU\deps\build.log`?

Up to now I’m also gettinh errors while installing other packages.

I’m going to uninstall everything and clean all folders and try again.

Looking into `c:\Users\username\.julia\packages\GR\k8wwU\deps\build.jl`  
it is trying to download  
[https://gr-framework.org/downloads/gr-0.35.0-Windows-x86\_64.tar.gz](https://gr-framework.org/downloads/gr-0.35.0-Windows-x86_64.tar.gz)  
You can try this in your browser.  
The julia command line used is (line 93 in build.jl)

```julia
file = "downloads/gr-0.35.0-Windows-x86_64.tar.gz"
download("https://gr-framework.org/downloads/gr-0.35.0-Windows-x86_64.tar.gz", file)

```

You can try this in the REPL. Remove `"downloads/"` from `file`, as the folder probably doesn’t exist in your current path.

I’ll download all needed packages. How should I continue with the installation from that packages?  
Anyway if I need to do it manually for every package it’s going to be very messy.

It was meant to check if there is some system problem with downloading, not that you download the tar archives manually.

I can download them well.

Can I force Julia to use another protocol?  
It seems to be something related with access permisions even if I run it as administrator.

In file  
`c:\Users\username\.julia\packages\GR\k8wwU\deps\build.jl`  
add line 96: `@info("https://$url")`  
It should look like;

```julia
    try
      @info("https://$url")
      download("https://$url", file)
    catch

```

Run

```julia
using Pkg
Pkg.build("GR")

```

Show us the output of  
`c:\Users\username\.julia\packages\GR\k8wwU\deps\build.log`

For me it shows:

```julia

The two first lines are Spanish (like my Windows) and mean

> it’s not possible to start Windows PowerShell version 3. It’s not installed properly

I don’t know what are those Chinese symbols, Google Translate is not able to translate them.

I’m going to try to install Powershell 3 but anything I try it says it’s not compatible.

In this case, the commands

```julia
file = "gr-0.35.0-Windows-x86_64.tar.gz"
download("https://gr-framework.org/downloads/gr-0.35.0-Windows-x86_64.tar.gz", file)

```

should also not work, I guess. You said, they are working?

You could try to install PowerShell 3:

> **[Download WMF 3.0 from Official Microsoft Download Center](https://www.microsoft.com/en-us/download/details.aspx?id=34595)**
>
> Includes Windows PowerShell 3.0, WMI, WinRM, Management OData IIS Extension, and Server Manager CIM Provider

But I am only guessing here, it seems strange.

OK, I’m sorry I was wrong.  
What I tried before was to download the file from a web browser, and that works.  
But if I run that lines from Julia I get this error:

I’ve being trying for a while and finally got to install

The more I learn about computers the more complex everything seems, crosscompilations, dead libraries, missing packages… and even more problems on Linux.

Anyway, now it works.  
Thank you.

That’s soooo crazy! Looks like we should even use our own (static builtin) download mechanism in `GR` …  
Anyway, thanks for finding this out.

Finally I found my problem was general, not just for GR.  
I’m going to change the thread title.  
Isn’t it possible to install the packages precompiled?
