Hi, i’m new to the community and this is the first time using Julia languege, so i’m at the beginig.

My problem is the follow:

```julia

What happens if you run

```julia
using Pkg
Pkg.build(“IJulia”)

```

as suggested by the error?

I don’t know if this information could help you.

I don’t know much about Windows 7, and I guess not many people do these days given it’s past its end of life, but did you look at the windows 7 specific installation instructions here [Platform Specific Instructions for Official Binaries](https://julialang.org/downloads/platform/#windows_7_windows_server_2012_installation_notes)?

I see your error is powershell related so that might have something to do with it?
