With some packages I have tried to install, I get an error as follows:

 ![curlProblem](https://global.discourse-cdn.com/julialang/original/3X/f/b/fbad9ae7a1e845a4c7a0ad38d47ad2be9e010dc4.png)

In another thread I have been told that probably my files `curl.exe` and/or `powershell.exe` are broken. I have checked and they seem to work fine. Also, I have tried in 5 different computers under Windows (laptops, desktops and a workstation) and in all cases I get the same error message, what would it be the probability that `curl.exe` and/or `powershell.ese` are broken in 5 out of 5 computers picked at random? 🤔

For the record, I am not a computer specialist, I’m a statistician that is trying to move from R to Julia, but I have been stuck with this issue for several weeks 😢 I have tried of course to ask about this here and in stackoverflow, tried whatever has been recommended to me, with no success, perhaps because I am not a computer science guy. I would really appreciate any suggestion for this matter, even if it impplies to pay by the hour to a computer professional for remote assistance. I’m using JuliaPro version 1.2.0. Thanks in advance.

For the error message it seems that curl has an issue with the certificate of [https://repo.continuum.io](https://repo.continuum.io)  
Can you try to open the URL in the browser?  
Or better try the curl command from the line “ERROR: failed process: …” in a command line or poershell command line and see what happens.

But I got the same error with another package that doesn’t need Anaconda, and yes, I can open such link form my browser, no problem at all.

And trying the curl command in a command line? This:

I think it is related to this similar issue:  
[https://stackoverflow.com/questions/54938026/curl-unknown-error-0x80092012-the-revocation-function-was-unable-to-check-r](https://stackoverflow.com/questions/54938026/curl-unknown-error-0x80092012-the-revocation-function-was-unable-to-check-r)

So putting a --ssl-no-revoke would help, but how to bring into the miniconda install script could be tricky.

The --ssl-no-revoke did not work 😢

The correlation could be quite high if they are the same version and setup of Windows & Julia, or used on the same network which has some restriction, etc.

As @oheil suggested, it may be best to try running the exact same shell command (highlighted in red, after `Process`), and debugging from there.

I would also just use plain Julia, not JuliaPro, to eliminate one source of variation in your setup.

Finally, the error message being in Spanish implies that seeking help locally (from IT, if this is an institutional/professional setting) may be better.

Two different computers at work, Windows 7, my computer at home Windows 10, and two friends’ personal laptops. Same result.

Also tried in plain Julia:

curl: (3) Port number ended with '\'
curl: (35) schannel: next InitializeSecurityContext failed: Unknown error (0x80092012) - La función de revocación no puede comprobar la revocación para el certificado.

```

After going through all this, it’s clear for me that Julia is for computer pros, not for a statistician like me. I think I’ll go back to R where I never had to struggle with this kind of details just to install a single package 😢

You didn’t paste the correct command line. Just run

```julia

Julia is open source, your help in tracking this down will make it easier for the next person.

No, it would be much easier, if you would do, what we try to tell you. We try to get as much information as possible to understand your issue.

Now, again, please call the curl command in red, which is part of your original output in the julia REPL.

it starts with:  
c:\windows\system32\curl.exe -s -S … and so on the rest  
@Tamas_Papp has read an written everything from your screenshot, which is tedious. You must only copy paste, this is not a Pro thing.

I was having a similar issue trying to properly install `Plots.jl` and I just solved it using a @giordano 's fork, so it seems that the problem is not with my `curl.exe` see:

Adding --insecure to the command line work. Could you try the following command in a windows cmd shell:  
`curl.exe --insecure -s -S -g -L -f -o "C:\Temp\installer.exe" https://repo.continuum.io/miniconda/Miniconda3-4.5.4-Windows-x86_64.exe`

Use another path, if you dont have c:\temp for the output file.

The above, after doing in Windows terminal:

```julia-auto
C:\>curl.exe --insecure -s -S -g -L -f -o "C:\Temp\installer.exe" https://repo.continuum.io/miniconda/Miniconda3-4.5.4-Windows-x86_64.exe

C:\>curl -V
curl 7.55.1 (Windows) libcurl/7.55.1 WinSSL
Release-Date: [unreleased]
Protocols: dict file ftp ftps http https imap imaps pop3 pop3s smtp smtps telnet tftp
Features: AsynchDNS IPv6 Largefile SSPI Kerberos SPNEGO NTLM SSL

```

The above results are form JuliaPro. Now in plain Julia I get:

```julia-auto

It seems we are step further.  
The new errors are obscure, so maybe we need to start in a new and clean environment.  
It seems in your environment there are things quite different to the default installation, but it is maybe the JuliaPro version 1.2.0 environment, which looks like this.

The output name c:\temp.… was just for testing, to see if the download works in general.

Please try now:

```julia
curl.exe --insecure -s -S -g -L -f -o "C:\Users\aerde\.julia\conda\3\installer.exe" https://repo.continuum.io/miniconda/Miniconda3-4.5.4-Windows-x86_64.exe

```
