I’m trying to install Pkg.add(“DataFrames”) but I get the following message. Any idea what could be the problem?

Looks like a network glitch. Check that `github.com` is reachable, eg with `ping`, then try again.

The error message seems different from what the “easy fix” fixes.

I think you are correct. I deleted my post.

Thank you for your response. I tried _ping_ and it seems that I have connection with [gitbub.com](http://gitbub.com)  
I tried again Pkg.add(“DataFrames”) and I got the same error message.

Follow the **manual** fix in this post, **not** the **“easy fix”**

solution

[Update to enable TLS 1.1 and TLS 1.2 as default secure protocols in WinHTTP in Windows](https://support.microsoft.com/en-us/help/3140245/update-to-enable-tls-1-1-and-tls-1-2-as-a-default-secure-protocols-in) The quick-fix didn’t patch the Webio.dll and the Winhttp.dll in the Windows-folders. So I went to the update-catalog and downloaded the proper file for my system: [Microsoft Update Catalog](https://www.catalog.update.microsoft.com/search.aspx?q=kb3140245) Patched,restarted, works.

I’m reviving this post.  
I’m on windows 8 and the proposed solutions do not work for me.

In the list given at [https://www.catalog.update.microsoft.com/search.aspx?q=kb3140245](https://www.catalog.update.microsoft.com/search.aspx?q=kb3140245) , none of the updates seem to apply to windows 8. I updated to .Net 4.5, but to no avail.  
I would really appreciate some help.  
Many thanks in advance  
Olivier

I would try either this:

> Update für Windows Embedded 8 Standard für x64-Systeme (KB3140245)

or this:

> Update für Windows Embedded 8 Standard (KB3140245)

depending on your system (32/64 Bit Version).  
The quick fix didn’t work for my systems, hence the workaround for a manual patch. I don’t know what the patches do in particular, but the registry hacks in the kb-article didn’t succeed either:

Thanks for your reply.

Unfortunately KB3140245 does not work.

I don’t see any other options.  
I will contact my system administrator.
