Dear all,  
I just to install Julia in a new computer.  
When I run `Pkg.add("JuMP")` a error message appears:

```julia

I don’t know the solution but does this happen with any package you try to install, or just Jump? I have a vague recollection about git doing weird things on Windows, but I don’t remember if there’s a solution.

I googled “juliapro windows GitError(EMERGECONFLICT” and found [this](https://github.com/JuliaLang/Pkg.jl/issues/1161#issuecomment-484162845), maybe give that a try?

Dear friend,  
Happens with any package.  
In this computer, I optimized some resourses in the windows.  
Would be this?

Could be. I don’t know enough about windows to know for sure, but deleting that directory shouldn’t be a problem. I’d give it a try and report back.

This is a bug in the version of JuliaPro you’re running.

There are two ways to fix this:  
a) Upgrade to JuliaPro 1.0.5.2.  
b) If you want to stay on the same version, go to `C:\Users\Usuário\.juliapro\JuliaPro_v1.0.4.1\registries\JuliaPro` and run

```julia
git config core.fileMode false

```

if you have git installed. otherwise you’ll need to edit `C:\Users\Usuário\.juliapro\JuliaPro_v1.0.4.1\registries\JuliaPro\.git\config` and add or change the `filemode` flag to `false`. The file should contain

```julia
[core]
	filemode = false

```

afterwards.
