I have been trying to find a fix for this issue for awhile. Perhaps this is a bug or my Windows has an issue. I have Powershell/curl on path along with 7z and tar. Am on Win 10 machine. I am able to run powershell and 7z from cmd using `powershell` and `7z` . Furthermore, I can run powershell and 7z inside Julia using run( `powershell` ) and run( `7z` ).

```julia
(@v1.4) pkg> add Example

If we look at probe\_platform\_engines we get the following info:

Lets focus on the first problem first, the download engine.

In the Julia REPL what is your output of:

```julia
julia> ENV["PATH"]

```

You may try to set the download engine explicit with e.g.:

```julia
julia> ENV["BINARYPROVIDER_DOWNLOAD_ENGINE"]="c:\\Windows\\System32\\curl.exe"
"c:\\Windows\\System32\\curl.exe"

```

Trying your suggestion gives a similar error to the original:

EDIT: I made `PATH["BINARYPROVIDER_DOWNLOAD_ENGINE"] = "curl"` which gets rid of the warning and searches for curl but alas we get the same error.

Your ENV[“PATH”] has some issues.  
E.g. there are entries like:  
`C:\\Users\\Zac\\AppData\\Local\\JuliaPro-1.4.2-1\\Julia-1.4.2\\bin\\7z.exe`

If you want `7z.exe` to be found automatically, your PATH entry should be:  
`C:\\Users\\Zac\\AppData\\Local\\JuliaPro-1.4.2-1\\Julia-1.4.2\\bin`  
without the exe itself (`7z.exe`).

Have you already tried to adjust your `PATH`? Do some clean up with this in mind. The same issue is for  
`C:\\WINDOWS\\System32\\WindowsPowerShell\\v1.0\\powershell.exe`  
Put  
`C:\\WINDOWS\\System32\\WindowsPowerShell\\v1.0`  
into your `PATH`.

So I was actually using both the path and executable entries. I have removed the executable entries. The issue remains however. Very strange since I can run powershell from cmd and even Julia using run.

Do you get true if

```julia

true

```

?

Okay this is abit more interesting:

And with complete path?

```julia

true

julia> success(Cmd(`C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell`))
true

```

If this errors again, I would first try to install powershell again:

> **[Installing Windows PowerShell - PowerShell](https://docs.microsoft.com/en-us/powershell/scripting/windows-powershell/install/installing-windows-powershell?view=powershell-7)**
>
> This article explains how to install Windows PowerShell on various versions of Windows.

You may also try whats described in this link, like finding and version of powershell and see if everything is normal.

Neither of those work either. I have disabled and reinabled powershell through windows (as this seems to be the only way to ‘reinstall it’ since that website is for updating PS on older OS - I think). Still no success. I have also reordered relevant paths from path variable and deleted any duplicates.

🤔

Does any windows command work from the Julia REPL? Like

```julia
success(Cmd(`C:\\Windows\\System32\\cmd.exe`))

```

Could you try another command in another path? E.g. copy cmd.exe to c:\temp and do a

```julia
success(Cmd(`c:\\temp\\cmd.exe`))

```

I am running out of ideas.

Neither of those work… 😓

It might be worth noting that the run command works fine. Eg. `run(`cmd`)`.

Do you mind to download and install plain Julia from here

> **[Download Julia](https://julialang.org/downloads/)**
>
> The official website for the Julia Language. Julia is a language that is fast, dynamic, easy to use, and open source. Click here to learn more.

If, e.g.  
`add DataFrames`  
is working here, than we know it isn’t your Windows which causes problems.

Nope, still the same error. ☹ Something very wrong with my OS.

Is this somehow some kind of high security environment? Something (or everything) blocked by your IT department? Anything like that? Perhaps I am complete on the wrong track, I don’t know.

It’s a home desktop and I’m at a loss for what it could be at this point. Is the difference between the success and run functions… It’s very strange that one throws and error whilst the other does not.

Could you run Julia with Administrator privileges and try again?

Nope, no luck. Here is issue on GitHub if you see anything that might help

To dive deeper into your issue, please restart your PC in safe mode **WITH Network drivers**.

To do this the easiest is method 6. Use “Shift + Restart” on the Windows 10 Start Menu:

> **[How to start Windows 10 in Safe Mode (9 ways) - Digital Citizen](https://www.digitalcitizen.life/4-ways-boot-safe-mode-windows-10/)**
>
> If you’ve been using Windows 10 for a while, you might have noticed that pressing the F8 or the SHIFT + F8 keys on your keyboard to enter Safe Mode no longer works. That method stopped working because the Windows 10 start procedure became faster than...

Read the complete description of method 6, before you actually do it, because you have to know which path to go.

Once in safe mode **WITH Network drivers** start a plain REPL (not Atom) and try again to add a package from the repository, e.g.:

```julia
]add DataFrames

```

I have tried the same on my PC and I did an

```julia
]up

```

in safe mode. It happily updated some packages from github.

Lets see if we can narrow it down…

For anyone who comes across this issue, it can be resolved by deleting the .julia files and doing a fresh install of julia. I can’t believe I didn’t try this originally - only just stumbled across the files.
